Search doesn't handle really short words properly

[bharat]

Steps to reproduce:
1) Create an item with the title "Per"
2) Search for "Per"

It doesn't show up because the FullText? match query:

SELECT g3_items.*, MATCH(g3_search_records.data) AGAINST ('Per') AS score FROM g3_items JOIN g3_search_records ON (g3_items.id = g3_search_records.item_id) WHERE MATCH(g3_search_records.data) AGAINST ('Per' IN BOOLEAN MODE) ORDER BY score DESC LIMIT 10 OFFSET 1;

doesn't do well with short words.

Perhaps if the keywords is less than 4 characters, don't use the fulltext index. This will result in weird results, perhaps.

Alternatively, let the user know that their search string was too short.
