[ECODP-dev] CKAN wild character for search

[John Glover]

Hi Bert,

Yes, the poverty vs poverties example will be covered by the stemming in
Solr.

In general, wildcard searches are not supported as we use the dismax query
parser[1].

However, if you search for a specific field by entering something like
"title: pov*" (without the quotes), it will actually be possible. This is
because if we detect a ":" character in the query, we fall back to using
the default query parser which does support wildcards. But yes, it does not
support wildcards at the start of terms.

Regards,
John
