Thanks James for the heads up and apologies for a delayed response.Here's the full details about this issue. Mine is an e-com app so the index contains the product catalog comprising roughly 13million products. At this point I thought of using the index based dictionary as the bet option for the "Did you Mean" functionality. I am not sure if every one facing this issue, but here is what I am observing as far as dictionary is concerned.
Index based dictionary - I was building the dictionary using the following url, once I completed the full indexing. For the time being I have kept the buildOnCommit and buildOnOptimize options intentionally to false, as I didn't want it to slow down the full indexing. http://localhost:8090/solr/select?rows=0&spellcheck=true&spellcheck.build=true&spellcheck.dictionary=jarowinkler - Once I created the dictionary when I tried to re-start my tomcat, I am facing the issue which I have stated before (I was waiting for around 20mts, the restart didn't happen). - When I removed the dictionary from the "data" folder, the server restart started working. - I have tried the spellcheck.collation=false as you suggested, but it didn't help. Direct Spell Checker I have experimented with the new "DirectSolrSpellChecker", where it does not create a separate dictionary folder, rather build the spellchecker in the main index itself. The results were exactly same as before, I was getting stuck during the restarts. I think the traditional spellchecker would be better in this case, as you can remove, restart and move back the dictionary as and when required. Where in case of DirectSolrSpellChecker, it doesn't create a separate dictionary folder, so not sure what to remove from the index, so that server can restart. James, I will request you to validate this, and it will be really great help if you can point out if I am doing any mistakes here. If you think what I am doing make sens, I will go ahead and log this bug in JIIRA.
