Paging @seamusabshere, any objections to merging this? |
|
It appears this gem has gone fallow/neglected, which is too bad because it's a great place to start with for its purpose. I am using this patch from @rlue in an app and it definitely improves my matching for strings with short tokens. |

hey @rlue @karpet , sorry for the abandonware. ASAP, i'll update this to use https://github.com/seamusabshere/pg_trgm internally - replacing dice's (aka bigram) and levenshtein, and proven to work like postgres |
