I presume your field is a TextField, by default solr does a fuzzy search on this field. What you want is to set up your field as a string field and add no tokenizer then you’ll get an exact match. You can even combine the exact search with a fuzzy search and use DisMax to … Read more
Websolr provides a cloud-based Solr with a control panel. It’s in private beta as of this writing, but you can get the service through Heroku. Another hosted Solr service is PowCloud, also in private beta, which seems to offer strong WordPress integration. SolrHQ: another beta service providing a hosted Solr solution, with Joomla and WordPress … Read more
Kind of depends on your requirements, but as far as I know there is no specific support for this in Solr. You can however hack it together in a few other ways. Not sure what you can expect for performance for these, tho.. Use Highlightning If you use highlighting you can parse the returned highlighted … Read more
That is correct. Typically you will want your field to be either indexed or stored or both. If you set both to false, that field will not be available in your Solr docs (either for searching or for displaying). See Alexandre’s answer for the special cases when you will want to set both to false. … Read more
This is a great question, something I have pondered over quite a bit. I will summarize my lessons learned: You can easily use Lucene/Solr in lieu of MongoDB for pretty much all situations, but not vice versa. Grant Ingersoll’s post sums it up here. MongoDB etc. seem to serve a purpose where there is no … Read more
Faceting would get you a results set that contains distinct values for a field. E.g. http://localhost:8983/solr/select/?q=*%3A*&rows=0&facet=on&facet.field=txt You should get something back like this: <response> <responseHeader><status>0</status><QTime>2</QTime></responseHeader> <result numFound=”4″ start=”0″/> <lst name=”facet_counts”> <lst name=”facet_queries”/> <lst name=”facet_fields”> <lst name=”txt”> <int name=”value”>100</int> <int name=”value1″>80</int> <int name=”value2″>5</int> <int name=”value3″>2</int> <int name=”value4″>1</int> </lst> </lst> </lst> </response> Check out the wiki for … Read more
A multivalued field is useful when there are more than one value present for the field. An easy example would be tags, there can be multiple tags that need to be indexed. so if we have tags field as multivalued then solr response will return a list instead of a string value. One point to … Read more
As you’re on a shared Linux box, you’ll have to ask the system administrator to do the following, probably. Create a startup script in /etc/init.d/solr. Copy this code, my Solr startup script, into that file: #!/bin/sh # Prerequisites: # 1. Solr needs to be installed at /usr/local/solr/example # 2. daemon needs to be installed # … Read more
I don’t know why that doesn’t work, but this one is logically equivalent and it does work: -(myField:superneat AND -myOtherField:somethingElse) Maybe it has something to do with defining the same field twice in the query… Try asking in the solr-user group, then post back here the final answer!
Update Now that the question scope has been corrected, I might add something in this regard as well: There are many comparisons between Apache Solr and ElasticSearch available, so I’ll reference those I found most useful myself, i.e. covering the most important aspects: Bob Yoplait already linked kimchy’s answer to ElasticSearch, Sphinx, Lucene, Solr, Xapian. … Read more
