bba4e0b529 Accept file deletion requests by clients during sync
- Remove unused full_corpus boolean. The full_corpus=False code path
  wasn't being used (accept for in a test)
- The full_corpus=True code path used was ignoring file deletion
  requests sent by clients during sync. Unclear why this was done
- Added unit test to prevent regression and show file deletion by
  clients during sync not ignored now

86575b2946 Chunk text in preference order of para, sentence, word, character
- Previous simplistic chunking strategy of splitting text by space
  didn't capture notes with newlines, no spaces. For e.g in 

- New strategy will try chunk the text at more natural points like
  paragraph, sentence, word first. If none of those work it'll split
  at character to fit within max token limit

- Drop long words while preserving original delimiters

a474c31e02 Move the django app into the src/khoj folder for better organization and functionality
- Our pypi package currently does not work because the django app and associated database is not included. To remedy this issue, move the app into the src/khoj folder. This has the added benefit of improved organization of the codebase, as all server related code is now in a single folder
- Update associated file paths and system references

bcbee05a9e Rename DbModels Embeddings, EmbeddingsAdapter to Entry, EntryAdapter
Improves readability as name has closer match to underlying
constructs

- Entry is any atomic item indexed by Khoj. This can be an org-mode
  entry, a markdown section, a PDF or Notion page etc.

- Embeddings are semantic vectors generated by the search ML model
  that encodes for meaning contained in an entries text.

- An "Entry" contains "Embeddings" vectors but also other metadata
  about the entry like filename etc.

[Multi-User Part 3]: Separate chat sesssions based on authenticated users ()
- Add a data model which allows us to store Conversations with users. This does a minimal lift over the current setup, where the underlying data is stored in a JSON file. This maintains parity with that configuration.
- There does _seem_ to be some regression in chat quality, which is most likely attributable to search results.

This will help us with . It should become much easier to maintain multiple Conversations in a given table in the backend now. We will have to do some thinking on the UI.

[Multi-User Part 1]: Enable storage of settings for plaintext files based on user account ()
- Partition configuration for indexing local data based on user accounts
- Store indexed data in an underlying postgres db using the `pgvector` extension
- Add migrations for all relevant user data and embeddings generation. Very little performance optimization has been done for the lookup time
- Apply filters using SQL queries
- Start removing many server-level configuration settings
- Configure GitHub test actions to run during any PR. Update the test action to run in a containerized environment with a DB.
- Update the Docker image and docker-compose.yml to work with the new application design

e3cd8b4150 Only index files returned by input-filter globs in fs_syncer
Ignore .org, .pdf etc. suffixed directories under `input-filter' from
being evaluated as files.

Explicitly filter results by input-filter globs to only index files,
not directory for each text type

Add test to prevent regression

d9d133dfb9 Read text files as utf-8, instead of default os locale
On Windows, the default locale isn't utf8. Khoj had regressed to
reading files in OS specified locale encoding, e.g cp1252, cp949 etc.

It now explicitly uses utf8 encoding to read text files for indexing

* Initial version - setup a file-push architecture for generating embeddings with Khoj

88d1a29a84 Test index is stable for duplicate entries across regenerate, update

25a749ca1d Use the src/ layout to fix packaging Khoj for PyPi
- Why
  The khoj pypi packages should be installed in `khoj' directory.
  Previously it was being installed into `src' directory, which is a
  generic top level directory name that is discouraged from being used

- Changes
 - move src/* to src/khoj/*
 - update `setup.py' to `find_packages' in `src' instead of project root
 - rename imports to form `from khoj.*' in complete project
 - update `constants.web_directory' path to use `khoj' directory
 - rename root logger to `khoj' in `main.py'
 - fix image_search tests to use the newly rename `khoj' logger
 - update config, docs, workflows to reference new path `src/khoj'

7e9298f315 Use new Text Entry class to track text entries in Intermediate Format
- Context
  - The app maintains all text content in a standard, intermediate format
  - The intermediate format was loaded, passed around as a dictionary
    for easier, faster updates to the intermediate format schema initially
  - The intermediate format is reasonably stable now, given it's usage
    by all 3 text content types currently implemented

- Changes
  - Concretize text entries into `Entries' class instead of using dictionaries
    - Code is updated to load, pass around entries as `Entries' objects
      instead of as dictionaries
    - `text_search' and `text_to_jsonl' methods are annotated with
       type hints for the new `Entries' type
    - Code and Tests referencing entries are updated to use class style
      access patterns instead of the previous dictionary access patterns

  - Move `mark_entries_for_update' method into `TextToJsonl' base class
    - This is a more natural location for the method as it is only
      (to be) used by `text_to_jsonl' classes
    - Avoid circular reference issues on importing `Entries' class

02d944030f Use Base TextToJsonl class to standardize <text>_to_jsonl processors
- Start standardizing implementation of the `text_to_jsonl' processors
  - `text_to_jsonl; scripts already had a shared structure
  - This change starts to codify that implicit structure

- Benefits
  - Ease adding more `text_to_jsonl; processors
  - Allow merging shared functionality
  - Help with type hinting

- Drawbacks
  - Lower agility to change. But this was already an implicit issue as
    the text_to_jsonl processors got more deeply wired into the app
