SOLR partial string matching question

[Vladimir Sutskever <Vl...@jpmorgan.com>]

Hi,

Can you guys make a recommendation for which types/filters to use accomplish the following partial keyword match:


A. Actual Indexed Term:  "bank of america"

B. User Enters Search Term:  "of ameri"


I would like SOLR to match document "bank of america" with the partial string "of ameri"

Any suggestions?



Kind regards,

you want a combination of WhitespaceTokenizer and EdgeNGramFilter
http://lucene.apache.org/solr/api/org/apache/solr/analysis/WhitespaceTokenizerFactory.html
http://lucene.apache.org/solr/api/org/apache/solr/analysis/EdgeNGramFilterFactory.html

the first will create tokens for each word the second will create
multiple tokens from each word prefix

use the analysis link from the admin page to test your filter chain
and make sure its doing what you want.
