Settings Window

Introduction

LumiFind comes with optimal default settings, and like every MIDILLI product, it allows users to customize them to their needs. The Settings window provides a range of options to enhance your experience.

Currently it provides five sections:

• Generic Settings
• Model Settings
• Search Settings
• Analysis Settings
• Visual Settings
• Danger Zone

Generic Settings

Settings that apply to the entire software.

App Language

The language to be used for the LumiFind itself. This value is set on Welcome Wizard. Changing will require restart of the program.

Model Settings

Settings related to models used in the LumiFind.

Enable Document Model

Checking the box loads the document model at startup and activates the analysis of document files. Changing this setting requires restarting LumiFind.

AI Model for Documents

Specifies which model to use for document analysis. Changing the model requires re-analysis of all document files. If you are using the Pro Edition, voice and video analyses must also be repeated. You will be asked to confirm the deletion of existing analysis data before the change is applied. To see the default available models, see this page [TODO].

If to add/use your own model, see this page [TODO].

Enable Image Model (Pro Edition)

Checking the box loads the image model at startup and activates the analysis of image files. Changing this setting requires restarting LumiFind.

AI Model for Images

Specifies which model to use for image analysis. Changing the model requires re-analysis of all image files. You will be asked to confirm the deletion of existing analysis data before the change is applied. To see the default available models, see this page [TODO].

If to add/use your own model, see this page [TODO].

Enable Voice Model (Pro Edition)

Checking the box loads the voice model at startup and activates the analysis of voice files. Changing this setting requires restarting LumiFind.

AI Model for Voice

Specifies which model to use for voice and video analysis. Changing the model requires re-analysis of all voice and video files. You will be asked to confirm the deletion of existing analysis data before the change is applied. To see the default available models, see this page [TODO].

If to add/use your own model, see this page [TODO].

Enable Video Model (Pro Edition)

Checking the box loads the voice model at startup and activates the analysis of video files. Changing this setting requires restarting LumiFind.

There is no separate model selection for videos since it uses the model defined for the Voice.

Search Settings

Settings related to Search Mode of LumiFind.

Max Results

Defines the maximum number of results that can be displayed in the result window. Increase it if the results are not satisfactory. Default: 100

Max Results Per File

Specifies the maximum number of search results that will be displayed for each individual file. Default: 1

File Formats To Search

Determines which file types will be included in the search. If a new format is added in the Analysis Settings [TODO], it will automatically appear here. To add a new format, type the extension starting with a dot (e.g., .txt) and press "Add". To remove a format from appearing in the search results, select it from the table and press "Remove". If a format is not already in the Analysis Settings, adding it here will not display it. To temporarily hide a file format from the search results, use the "Filter..." button in the Search Mode.

File Size Limits

Sets the minimum and maximum file sizes that LumiFind will display in the search results. Files outside this range will be ignored. Default is between 0 and 100 MB.

Detail Level

Specifies the depth of search for files.

• Metadata and Content (default): Searches both metadata (e.g., file name, creation date, or other file properties not related to the actual content, similar to the operating system's search) and the file content itself using the selected model.

• Metadata Only: Searches only the file's metadata without analyzing the content.

• Content Only: Focuses solely on the file content, leveraging the model for deeper and more intelligent search results. Metadata will be ignored. For example, if a file is named abc.txt and you search for "abc", the file will only be found if the term "abc" or semantically related content exists within the document. If not, it will not appear in the search results.

Document Min Score

Specifies the minimum relevance score a document must have to appear in search results. Lower scores may include less relevant results and higher scores may end up not showing any files at all.

Image Top K (Pro Edition)

Determines how many top-matching images will be displayed for each image search query.

Analysis Settings

Settings related to Analysis Mode of LumiFind.

File Formats to Analyze

Determines which file types will be included in the analysis. If a new format is added in this section, it will automatically be added to Search Settings as well. To add a new format, type the extension starting with a dot (e.g., .txt) and press "Add". To remove a format from being analyzed, select it from the table and press "Remove". If a format is in the Search Settings, but not here, it will not be analyzed.

File Size Limits

Sets the minimum and maximum file sizes that LumiFind will process. Files outside this range will be ignored. Default is between 0 and 100 MB.

Document Chunk Size

Determines the maximum size of each document chunk when splitting files for analysis. Smaller chunks may improve search accuracy. Default: 500

Document Chunk Overlap

Specifies how much overlap there should be between consecutive document chunks. Overlap helps preserve context across chunks. Default: 50

Document Batch Size

Sets the number of document chunks processed together in a single batch. Larger batch sizes may speed up processing but use more memory. If you encounter out-of-memory errors, consider decreasing this value. Default: 1000

Image Batch Size (Pro Edition)

Determines how many images are processed together in a single batch. Larger batches may improve throughput but consume more resources. Default: 2

Voice Chunk Duration (sec) (Pro Edition)

Specifies the length in seconds for each segment of voice or video files during analysis. Shorter chunks may improve accuracy for long recordings. Default: 30 seconds.

Show Current File

When enabled, displays the file currently being analyzed in the interface. Default: No.

Treat Images as Documents

If enabled, image files included in File Formats to Analyze will be treated like documents, extracting any text or visual information where applicable. Default: No.

Warning: This will significantly increase the analysis time for each image due to the additional processing required.

Note: Windows users need to install Tesseract and GhostScript as described on this page. For Mac and Linux users, these tools are installed automatically.

Enable OCR fallback for PDFs

If enabled, LumiFind will attempt OCR (Optical Character Recognition) on PDFs that cannot be read natively, allowing extraction of text from scanned documents. Default: No.

Warning: This will significantly increase the analysis time for each image due to the additional processing required.

Note: Windows users need to install Tesseract and GhostScript as described on this page. For Mac and Linux users, these tools are installed automatically.

Visual Settings

Settings related to user interface behavior of LumiFind.

Log Level

Specifies the level of detail shown in the Logs. Available options:

• DEBUG – Shows detailed debugging information. Might be useful to get support from us.

• INFO – Shows general informational messages (Default).

• WARNING – Shows warnings about potential issues.

• ERROR – Shows only error messages.

File Size Unit

Determines the unit used to display file sizes. Options include B, KB, MB, and GB. Default: MB

Date Format

Specifies how dates are displayed in LumiFind. Options include:

• DD.MM.YYYY – Day.Month.Year. E.g., 26.11.2025

• MM/DD/YYYY – Month/Day/Year. E.g., 11.26.2025

• YYYY-MM-DD – Year-Month-Day. E.g., 2025-11-26

Time Format

Specifies how time is displayed in LumiFind. Options include:

• HH:mm:ss – 24-hour format with seconds (Default)

• HH:mm – 24-hour format without seconds

• hh:mm:ss AM/PM – 12-hour format with AM/PM and seconds

Danger Zone

The Danger Zone contains settings that can significantly affect LumiFind’s behavior or data. Make changes here with caution, as they may result in data loss or require reconfiguration.

Delete Document Model Data

Removes all stored document analysis data. After this action, every document must be analyzed again before it becomes searchable.

Delete Image Model Data (Pro Edition)

Clears all stored image embeddings and analysis results. Images will need to be reprocessed before they can appear in search results.

Delete Voice Model Data (Pro Edition)

Deletes all indexed voice and audio analysis data. Voice files must be reanalyzed to restore search functionality.

Delete Video Model Data (Pro Edition)

Removes all video analysis and indexing data. Videos will require full reprocessing before they can be searched again.

Open Settings Folder

Opens the application settings folder. Not dangerous at all. It's simply here because we had no better place to put it. Feel free to take a peek if you're curious about how tidy things are behind the scenes.

Reset LumiFind Settings

Deletes the LumiFind's settings file and restores the application to its initial state with the Welcome Wizard. Your analysis data will remain untouched.
