sorry if this is a very simple question, but I am stuck (and online searches for this info havent been fruitful).
Lets say that, in certain circumstances, I want to change the field names and/or field query values being passed to SOLR. For example, lets say my unmodified query is "http://localhost:8994/solr/select?q=xxx:[* TO 3] AND yyy:[3 TO *]&defType=myQParser" and (JUST for the sake of argument) lets say I want to rewrite it as "http://localhost:8994/solr/select?q=aaa:[1 TO 2] AND bbb:[3 TO 10]&defType=myQParser". I think I can do it by extending QParserPlugin, and overriding the createParser method (see my code snippet below). The qstr parameter apparently contains the parts I want to examine and/or modify. now to my questions: 1. is that the correct location to do this sort of manipulation? 2. is there an existing method for parsing out the fields and their parameters? i.e. to break a qstr of "xxx:[* TO 3] AND yyy:[3 TO *]" into an array something like x[0][0] = "xxx", x[0][1]="* TO 3", x[1][0] = "yyy", x[1][1]="3 TO *". Or possibly even finer granularity than that. I could write it myself but its much nicer not to have to (especially since the queries could be very complex). thanks in advance for any help. -------------------------------------------------------- package com.topproducer.rentals.solr.search; import org.apache.lucene.queryParser.ParseException; import org.apache.lucene.search.Query; import org.apache.solr.common.params.SolrParams; import org.apache.solr.common.util.NamedList; import org.apache.solr.request.SolrQueryRequest; import org.apache.solr.search.QParser; import org.apache.solr.search.QParserPlugin; public class myQParserPlugin extends QParserPlugin { @Override public QParser createParser(String qstr, SolrParams localParams, SolrParams params, SolrQueryRequest req) { return new QParser(qstr, localParams, params, req) { QParser baseParser; public Query parse() throws ParseException { StringBuilder queryBuilder = new StringBuilder(); // extract and/or view and/or change qstr content here // .. // is there an existing function/method to parse qstr into its component parts? // i.e. to break "?q=xxx:[1 TO 3] AND yyy:[3 TO *]" into something like: // x[0][0] = "xxx", x[0][1]="1 TO 3" // x[1][0] = "xxx", x[1][1]="3 TO *" // after modifying qstr, store it into queryBuilder here queryBuild.append(new_qstr); // prepare queryBuilder for any additional solr handling baseParser = subQuery(queryBuilder.toString(), null); Query q = baseParser.parse(); return q; } public String[] getDefaultHighlightFields() { return baseParser.getDefaultHighlightFields(); } public Query getHighlightQuery() throws ParseException { return baseParser.getHighlightQuery(); } public void addDebugInfo(NamedList debugInfo) { baseParser.addDebugInfo(debugInfo); } }; } @Override public void init(NamedList arg0) { // TODO Auto-generated method stub } } -- View this message in context: http://www.nabble.com/about-modifying-querystring-parameters-submitted-to-solr-tp25752898p25752898.html Sent from the Solr - User mailing list archive at Nabble.com.
