6. Searching Full text search http://localhost:8983/solr/select?q=Iraq  Search only within a field http://localhost:8983/solr/select?q=category:news  Control which fields are displayed in result http://localhost:8983/solr/select?q=video&fl=id,category  Provide ranges to fields http://localhost:8983/solr/select?q=price:[0 TO400]&fl=id,name,price By Mick England

7. More Searching Faceting information http://localhost:8983/solr/select?q=news&fl=id,description &facet=true&facet.field=category  More like this (MLT) http://localhost:8983/solr/select?q=Iraq&mlt=true&mlt.fl= headline&mlt.mindf=1&mlt.mintf=1&fl=id,score&rows=1 00 More information on how this works and the options available can be found at http://wiki.apache.org/solr/MoreLikeThis http://wiki.apache.org/solr/MoreLikeThis By Mick England

8. QueryResponseWriter  A QueryResponseWriter is a Solr Plugin that defines the response format for any request  All of the requests we have made so far are formatted with the XMLResponseWriter  Other formats can be applied by appending wt=format to the search string like this: http://localhost:8983/solr/select?q=date:[1998%20TO%201 999]&fl=id,name,date,headline&rows=200&wt=xslt&tr=ex ample.xsl By Mick England
