-------------------------------------
Summary: Allow FiltersQParser (`{!filters param=[...]}`) to
tolerate empty `param` args
Key: SOLR-16126
URL: https://issues.apache.org/jira/browse/SOLR-16126
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: query parsers
Affects Versions: main (10.0)
Reporter: Michael Gibney
One common use case for FiltersQParser is to bundle filters and main query,
e.g. for passing a single-query domain definition to functions, or for
finer-grained control over how logical filters are bundled together.
Consider the first use case: `\{!filters param=$q param=$fq\}`
FiltersQParser currently strictly enforces that the referred params must be
present and non-empty, and fails hard (throws a {{SyntaxError}}) if this is not
the case.
This issue proposes to relax this enforcement, because:
# There are legitimate, common use cases for which this requirement is simply
an inconvenience (albeit easily worked around by adding a "dummy"
{{fq=\*:\*}}), and
# It's unclear what practical purpose is served by by the current strict
enforcement of non-empty params.
The proposal is to have e.g. `\{!filters param=$fq\}`, in the absence of any
non-empty {{fq}} param, be equivalent to {{\*:\*}}.
