Hi Rocha, In your webapp I guess you have at list a view and a service layers. The indexing and search modules should preferably be hosted at the service layer. I recommend you read the Api doc ( http://lucene.apache.org/solr/4_2_1/solr-solrj/index.html) to get a sense of what you can do with SolrJ. Followinf is a Basic Example Facets with SolrJ: //adding the query keyword to the SolrQuery object mySolrQuery.setQuery(queryBuilder.toString()); // add a facet field mySolrQuery.addFacetField("myFieldName") //add a facet query validatedFromTheLast7DaysFacetQuery = validationDateField + ":[NOW/DAY-7DAY TO NOW]" mySolrQuery.addFacetQuery(validatedFromTheLast7DaysFacetQuery)
//send the request in HTTP POST as with HTTP GET you run into issues when the request string is too long. QueryResponse queryResponse = getSolrHttpServer().query(mysolrQuery, METHOD.POST); //write a transformer to convert the Solr response to a format understandable by the caller (the client of the search service) //List of results to transform SolrDocumentList responseSolrDocumentList = queryResponse.getResults(); //get the facet fields, interate over the list, parse each FacetField and extract the information you are intersted in queryResponse.getFacetFields() //get the facet query from the response Map<String, Integer> mapOfFacetQueries = queryResponse.getFacetQuery(); The keys of this map are your facet queries. The values are the counts you display to the user. In general, I have an identifier for each facetQuery. When I parse the keys of this map of facet queries, I return the identifier of each facet along with its count (if the count > 0 of course). The caller is aware of this identifier so it knows what to display to the user. When the user clicks on a facet, you send it as a search criteria along with the initial keywords to the search service. The criteria resulting from the facet is treated as a filter query. That is how faceting search works. Adding a filter to your query is as simple as this snippet mySolrQuery.addFilterQuery(myfilterQuery). should you are filtering because your user click on the previously defined facet query, then the filter query is the same as the facet query. that is myfilterQuery = validationDateField + ":[NOW/DAY-7DAY TO NOW]". I hope this helps.
