Hello Walter and Mikhail, Thank you for your answers. Do those spell checkers have the same or better fuzzy matching capability that SOLR/Lucene has (Lichtenstein, max distance 2)? That's a critical requirement for my application. I take it by your suggestion of these spell checker apps they

You can create a copy field with string type and make it copy from this existing field, and sort on this new one. That way, you can still continue doing text search on existing one and sort on this new field. On Fri, Oct 30, 2015 at 3:04 PM, Brian Narsi wrote: > Is there

Re: Fastest way to import a giant word list into Solr/Lucene?

Dedicated spell-checkers have better algorithms than Solr. They usually handle transposed characters as well as inserted, deleted, or substituted characters. This is an enhanced version of Levinshtein distance. It is called Damerau-Levenshtein and is too expensive to use in Solr search. Spell

Douglas, Managing a per-user-group whitelist of fields outside of Solr seems the best approach. When the query comes in you can then filter out any fields not contained in the whitelist before you send the request to Solr. The easy part will be to do that on URL parameters like fl. Depending on

bq: Is there no way that the existing field can be used? In a word, "no". The indexed terms are being used for sorting. You have a document that has the title "aardvark zebra". The actual _tokens_ are aardvark zebra solr/Lucene has no way of knowing whether these should be sorted by "a" or "z".

Just a suggestion Markus that sending 50k documents in your case worked but you may want to benchmark sending batches in 5K, 10k or 20k batches and compare with sending 50k batches. It may turn out that smaller batch size may be faster than very big batch size... On Fri, Oct 30, 2015 at 7:59 AM,

Glad you can solve it one way or the other. I do wonder, though what's really going on, the fact that your original case just hung is kind of disturbing. 50K is still a lot, and Yonik's comment is well taken. I did some benchmarking (not ConcurrentUpdateSolrServer, HttpSolrClient as I remember)

Solr Keyword query on a specific field.

Is there any way to have a single field search use the same keyword search logic as the default query? I define q.op as AND in my query which gets applied to any main keywords but any keywords I'm trying to use within a field do not get the same logic applied. Example: q=(title:(Test Keywords))
