[jira] Commented: (SOLR-357) Prefixing Filter Factory -- for 'suggest'

["Hoss Man (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12527793 ] 

Hoss Man commented on SOLR-357:
-------------------------------

isn't this a subset of the functionality in EdgeNGramFilterFactory ?

in answer to your followup questions:  

1) the easiest way i can think of to do this is with a boolean query on two fields -- one using KeywordTokenizer and the other using something else. "Canon PIXMA" would match on bth, "...video card" would only match on the second.

2) i'm not sure i understand the question, it sounds like you would just want a really sloppy phrase query, but i must be missing something.  should probably discuss outside of Jira.

> The PrefixingFilter builds a token for each prefix in the original token.  It is appropriate for a type-ahead suggest style function.
> Given the token "solr", this will build a token for "s","so","sol","solr".
