I want to be able to parse "KEY:VALUE" pairs from my text and have a facet representing distribution of VALUES On Mon, Jul 23, 2018 at 12:25 PM Markus Jelsma wrote: > Hello, > > Neither fl nor facet.field support functions, but facet.query is analogous > to the latter.

can it be used in facets? On Mon, Jul 23, 2018, 11:24 Markus Jelsma wrote: > Hello, > > It is not really obvious in documentation, but the standard query parser > supports regular expressions.

Can I use RegEx function?
I've got collection with a string or text field storing free-text. I'd like to use some RexEx function looking for patterns like "KEY:VALUE" from the text and use it for filtering and faceting.
Streaming Expressions (/stream) StreamHandler java.lang.NullPointerException
I've got an exception below running
curl --data-urlencode
'expr=search(EventsAndDCF,q="*:*",fl="AccessPath",sort="AccessPath
asc",qt="/export")' "http://localhost:8983/solr/EventsAndDCF/stream";
Solr responce:
{"result-set":{"docs":[
{"EXCEPTION":null,"EOF":true}]}}
My collection EventsAndDCF exists. and I succeed to run GET queries like:
http://localhost:8983/solr/EventsAndDCF/export?fl=AccessPath&q=*:*&sort=AccessPath
desc&wt=json
