Subject Re: Issue with if() statement
Date Fri, 01 Jan 2016 22:08:38 GMT
You've got to think of what the queries will be that you produce under
the bonnet - what you are talking about is either a (!func} or a
{!frange} query - both of which are inefficient as they must scan the
entire resultset.

However, what you're trying to do is evaluate the length of the *input
value*, not a value in the documents being searched, so this doesn't
really apply - you're talking about doing some work before your query
happens.

Again, I'm not sure of a way to do this on a stock Solr, but with a
little coding it should be achievable - you could extend the switch
query parser, or you could write your own - they're not that hard to
create. Or, you could create a search component that operates before the
QueryComponent does.

A simple queryparser of your own would seem like a pretty lightweight
thing - probably 20 lines of code or less.
