Bug: tag search matches on incomplete search terms in source

[jugaltheshah]

Came across a strange issue in using search-notes:

In my markdown file, I have a tag, #reviewfodder. I searched for it with the string "tags:reviewfodder" and it properly returned a hit for the file, but under the Hits section I noticed it seems to have matched on reviewfodd. Indeed, if in the matched markdown file, I remove a letter from the tag, i.e. #reviewfodde and search using the same query as before, "tags:reviewfodder", it still comes back with the same match. I confirmed that the file had no other strings #reviewfodder it should have matched on.

I thought there might have been an issue with the tag length so I tested this with another string but oddly it did not display the same behavior. For example, I put the tag #abcdefghijklmno in my markdown file and searched using "tags:abcdefghijklmno" -- this produced 1 result as expected. I then removed the last character, i.e. #abcdefghijklmn and repeated the search for "tags:abcdefghijklmno" -- this also correctly produced 0 results, as expected.

Not sure why it sometimes does incorrect / partial matching, but thought I'd report it.

This may have to do with the tokenizer used by the search engine. It tries to understand different word forms to some extent to do fuzzy matching.
