Having org-mode result headings change size based on their depth in
the source document makes is a confusing UI experience.
Improve font-size, line-spacing and margins of results to make
delineation between entries, and differntiating between entry heading
and it's body easier to visually infer.
Do not white-space: pre-line. Improves rendering of Markdown results
## Details
- We were previously just wrapping results from /search API into a pre formatted div field. This was not easy to read
- Use [markdown-it](https://github.com/markdown-it/markdown-it) to render markdown results from Khoj `/search` API as proper HTML
Closes#43
## Support Incremental Search on Khoj Web Interface
- Use default, fast path to query /search API while user is typing
- Upgrade to cross-encoder re-ranked results once user hits enter on search box
## Improve Render of Org Results on Web Interface
- We were previously just wrapping results from /search API into a pre formatted div field. This was not easy to read
- Use [org.js](https://mooz.github.io/org-js/) to render results from Khoj `/search` API as proper HTML
- Improve org.js to render all task states, stylize task tags and make org-mode results look more like original content
Closes#42#41
# Details
## Improve Search API Latency
- Improve Search API Latency by ~50-100x to <100ms
- Trade-off speed for accuracy in default, fast path of /search API by not re-ranking results using cross-encoder
- Make re-ranking of results via cross-encoder configurable via new `?&r=<false|true>` query param to /search API
- Only deep-copy entries, embeddings to apply filters if query has any filter keywords
## Support Incremental Update via Khoj Emacs Frontend
- Use default, fast path to query /search API while user is typing
- Upgrade to cross-encoder re-ranked results once user goes idle (or ends search normally)
Closes#37
In current state:
- Rerank results:
- If user idles while entering query OR
- exits normally
- Do not rerank results:
- If user exits abnormally, e.g via C-g from query
- Rename functions to more standard, descriptive names
- Keep known, required code for incremental search
- E.g Do not set buffer local flag in hooks on minibuffer setup
- Only query when user in khoj minibuffer
- Use active-minibuffer-window and track khoj minibuffer
- (minibuffer-prompt) is not useful for our use-case here
- (For now) Run re-rank only if user idle while querying
- Do not run rerank on teardown/completion
- The reranking lag (~2s) is annoying; hit enter,
wait to see results
- Also triggered when user exits abnormally,
so C-g also results in rerank which is even more annoying
- Emacs will still hang if re-ranking gets triggered on idle but
that's better than always getting triggered. And better than not
having mechanism to get results re-ranked via cross-encoder at all
- Update khoj-simple to work cross-encoder re-ranked results like before
- Increment major version as incremental search considered a breaking
change and a major update to search capability
- Improve search speed by ~10x
Tested on corpus of 125K lines, 12.5K entries
- Allow cross-encoder to re-rank results by settings &?r=true when querying /search API
- It's an optional param that default to False
- Earlier all results were re-ranked by cross-encoder
- Making this configurable allows for much faster results, if desired
but for lower accuracy
- Formalize filters into class with can_filter() and filter() methods
- Use can_filter() method to decide whether to apply filter and
create deep copies of entries and embeddings for it
- Improve search speed for queries with no filters
as deep copying entries, embeddings takes the most time
after cross-encodes scoring when calling the /search API
Earlier we would create deep copies of entries, embeddings
even if the query did not contain any filter keywords
- Reason:
Allow natural search on markdown based notes, documentation,
websites etc
- Details:
- Create markdown processor to extract Markdown entries (identified by
Heading) into standard jsonl format required by text_search
- Update API, Configs to support interfacing with new markdown type
- Update Emacs, Web clients to support interfacing with new markdown
type via API
- Update Readme to mentiond markdown is also supported
Closes#35
- The code for both the text search types were mostly the same
It was earlier done this way for expedience while experimenting
- The minor differences were reconciled and merged into a single
text_search type
- This simplifies the app and making it easier to process other
text types
Now that the logic to compile entries is in the processor layer, the
extract_entries method is standard across (text) search_types
Extract the load_jsonl method as a utility helper method.
Use it in (a)symmetric search types
- The logic for compiling a beancount entry (for later encoding) now
completely resides in the org-to-jsonl processor layer
- This allows symmetric search to be generic and not be aware of
beancount specific properties that were extracted by the
beancount-to-jsonl processor layer
- Now symmetric search just expects the jsonl to (at least) have the
'compiled' and 'raw' keys for each entry. What original text the
entry was compiled from is irrelevant to it. The original text
could be location, transaction, chat etc, it doesn't have to care
- The logic for compiling an org-mode entry (for later encoding) now
completely resides in the org-to-jsonl processor layer
- This allows asymmetric search to be generic and not be aware of
org-mode specific properties that were extracted by the org-to-jsonl
processor layer
- Now asymmetric search just expects the jsonl to (at least) have the
'compiled' and 'raw' keys for each entry. What original text the
entry was compiled from is irrelevant to it. The original text
could be mail, chat, markdown, org-mode etc, it doesn't have to care
- Pass Scheduled, Closed Dates of Entries to Include in Embeddings
- The (new?) model seems to understand dates. So can give more
relevant entries if date in natural language mentioned in query
- E.g "Went Surfing with Friends" vs "Went Surfing with Friends in 1984"
will give different results, with the second prioritizing entries
mentioning any entries with closed, scheduled dates from 1984
- While it's true those strings are going to be used to generated
embeddings, the more generic term allows them to be used elsewhere as
well
- Their main property is that they are processed, compiled for
usage by semantic search
- Unlike the 'raw' string which contains the external representation
of the data, as is
- Had already made some progress on this earlier by updating the image
search responses. But needed to update the text search responses to
use lowercase entry and score
- Update khoj.el to consume the updated json response keys for text
search
