Subject [jira] [Commented] (SOLR-8488) Add support for leading wildcards to ComplexPhraseQParserPlugin
Date Thu, 07 Jan 2016 20:10:39 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15088019#comment-15088019

Yonik Seeley commented on SOLR-8488:
------------------------------------

For a common letter such as "a", each level may be 10 times more expensive than the last...
while it may make sense to *allow* for that to be limited, I don't think it makes sense to
hobble it by default.  Its also not necessarily that expensive compared to some other Solr
operations like stats/facets on high cardinality fields (and pivoted multiplies this).

Solr has normally allowed leading wildcards by default, and we should continue that here.
For example, try:
http://localhost:8983/solr/techproducts/query?q=text:*olr

> It would be useful to support leading wildcards in phrase searches as well. 
> Currently we support this query -
> {code}{!complexphrase inOrder=true}name:"Jo* Smith"{code}
> It would be useful to be support a query like -
> {code}{!complexphrase inOrder=true\}name:"*Jo* Smith"{code}
