Description

Currently ComplexPhraseQParser (SOLR-1604) allows trailing wildcards on terms in a phrase, but does not allow leading wildcards. I would like the option to be able to search for terms with both trailing and leading wildcards.

For example with:

{!complexphrase allowLeadingWildcard=true}

"j* *th"
would match "John Smith", "Jim Smith", but not "John Schmitt"
