Solrj: how to specify path

I'm try开发者_StackOverflow社区ing to use the TermsComponent to implement autosuggest with Solrj, but I don't see how to specify the path (i.e. the /terms portion of http://localhost:8983/solr/terms).

How can I specify the path using Solrj?

Bonus: is there a way to specify multiple fields for the terms.fl param?

Thanks

Here we go:

    SolrQuery query = new SolrQuery();
    query.setParam(CommonParams.QT, "/terms");
    query.setParam(TermsParams.TERMS, true);
    query.setParam(TermsParams.TERMS_LIMIT, "10");
    query.setParam(TermsParams.TERMS_FIELD, "title", "description");  // or whatever fields you want
    query.setParam(TermsParams.TERMS_PREFIX_STR, typedInput);

This is assuming that you have the TermsComponent wired in at "/terms"; the default solrconfig.xml has it there.

And for the bonus: you can add multiple fields simply by adding multiple strings for TERMS_FIELD (or multiple URL &terms.fl=foo params).

Thank you Mauricio, for pointing me in the right direction.

Direct support for TermsComponent is not available in SolrJ 1.4.1, but take a look at the corresponding patch, it's pretty easy to implement it yourself.

Since TermsComponent is a standard component you don't need to use /terms, you can hook it to the standard query request handler.

I spend so much time to make the TermsComponent work.

At the end of the day, I realized that there is a different set of commands that you need to invoke in order to retrieve the results from the "/terms" requestHandler.

I was trying to get the results using

HttpSolrServer server = new HttpSolrServ(solrUrl);
List<SolrDocument> list = server.query(query).getResults()

However, the correct way to get the results from the TermsComponent is

HttpSolrServer server = new HttpSolrServ(solrUrl);
TermsResponse termResp = server.query(query).getTermsResponse();
List<Term> tList = termResp.getTerms("fieldNAME");

I hope this may help someone else in the future.
