How much is the maxEdits you have set. It should catch restaurant example with edit distance set to 2.

Direct works fine most of the time, but I'd like to find solution for few corner cases: 1) having "recruted" and "recruiter" in index, "recruter" should suggest the latter. Obviously the distance to the former is smaller, so it may be completely arbitrary, and perhaps must be handled on application side rather then solr. 2) "restraunt" doesn't suggest "restaurant" - I assume that distance is to big for that. Those are few examples of queries that spellcheck gets (according to my requirements) wrong. For now I am just looking at possible solutions and I'd need to come up with initial concept to have something to show to users and get more feedback, likely with more cases to correct. I'd like to know if there are some tweaks to spellcheck component I could make (or perhaps other ways of doing this with solr), or am I forced to hardcode list of all such corrections that go beyond what spellcheck can do? One solution I am considering is to put list of those special cases into FileSpellChecker (it seems to be more relaxed, and handles restraunt case well) and fall back to Direct if this yields no results... though I am not sure yet how well that would work in practice if the list of misspelled words would grow beyond few I have now. It would most likely woldn't scale Another possibility would be to analyze list of queries our users use that yield little results and check if there is spellchecked version that improves that... but that seems to require human to review corrections. Yet another thing I was thinking about would be to pull terms into separate spellchecker (like aspell) and see if they do better job or are more tweakable. That's a bit open ended problem, so any advice welcome. -- Maciej Dziardziel fied...@gmail.com This e-mail message may contain confidential or legally privileged information and is intended only for the use of the intended recipient(s).
