: timeAllowed does not limit spellcheck i have tried.
Hmmm .... that doesn't sound right -- unless you are using a really old version of solr, any index based spellchecker (like Direct and WordBreak) should be respecting timeAllowed due to the underlying Lucene IndexReader enforcing it. - What version of solr are you using? - do you have enough query volume (and do these time outs happen often enough) that you can take a lot of threaddumps and identify any "hot spots" in the spellchecking code? - if the problem is sporadic, do you see any "patterns" in the reuests that cause the problem (i'm specifically wondering about long query strings that might be triggering the WordBreak bug i linked to before) - have you tried only using only one dictionary or the other to narrow down the problem? - I know it comes from a documented example, but maxChanges=10 with WordBreak is excessive for most "real world" word combinations i've seen in practice, and exacerbates the problem in the WordBreak bug i linked to before. does lowering that to something like2 or 3 reduce this problem? : : Following are the spellcheck configuration.
