Hi *,
I implemented a custom filter and am using it through a QParserPlugin. I'm
wondering however, whether my implementation is that clever yet...
Here's my QParser; I'm wondering whether I should apply the filter to all
documents in the index (I already guess it's a bad idea) or whether I should
use the query as provided by the already available query parser, see the
parse() method.
public AccessFilterQParser(String qstr, SolrParams localParams,
SolrParams params, SolrQueryRequest req) {
super(qstr, localParams, params, req);
QParserPlugin parserPlugin =
req.getCore().getQueryPlugin(QParserPlugin.DEFAULT_QTYPE);
QParser parser = parserPlugin.createParser(qstr, localParams,
params, req);
try {
preConstructedQuery = parser.getQuery();
} catch (ParseException e) {
throw new RuntimeException(e);
}
String fieldName = localParams.get(AccessParams.ACCESS_FIELD,
"access");
this.accessFilter = new AccessFilter(fieldName, qstr);
}
@Override
public Query parse() throws ParseException {
Query allDocs = new MatchAllDocsQuery();
// return new FilteredQuery(allDocs, accessFilter);
return new FilteredQuery(preConstructedQuery, accessFilter);
}
I'd be happy about any advice...
best
Ingo
