I've tried to use the solr.SuggestComponent as stated in the website, but it couldn't work.
When I change to using the suggest with the configuration below and go a query like http://localhost:8983/solr/collection1/suggest?q=mater, it says "The Webpage cannot be found" <searchComponent class="solr.SuggestComponent" name="suggest"> <lst name="spellchecker"> <str name="name">suggest</str> <str name="classname">org.apache.solr.spelling.suggest.Suggester</str> <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str> <str name="field">text</str> <!-- the indexed field to derive suggestions from --> <str name="buildOnCommit">true</str> </lst> </searchComponent> <requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggest"> <lst name="defaults"> <str name="echoParams">explicit</str> <str name="defType">edismax</str> <int name="rows">10</int> <str name="wt">json</str> <str name="indent">true</str> <str name="suggest">true</str> <str name="suggest.dictionary">suggest</str> <str name="suggest.count">5</str> <str name="suggest.collate">true</str> </lst> <arr name="components"> <str>suggest</str> </arr> </requestHandler> Regards, Edwin On 4 June 2015 at 13:21, Erick Erickson <erickerick...@gmail.com> wrote: > This may be helpful: http://lucidworks.com/blog/solr-suggester/ > > Note that there are a series of fixes in various versions of Solr, > particularly buildOnStartup=false and working on multivalued fields. > > Best, > Erick > > On Wed, Jun 3, 2015 at 8:04 PM, Zheng Lin Edwin Yeo > <edwinye...@gmail.com> wrote: > > My previous suggester configuration is derived from this page: > > https://wiki.apache.org/solr/Suggester > > > > Does it mean that what is written there is outdated? > > > > Regards, > > Edwin > > > > > > > > On 3 June 2015 at 23:44, Zheng Lin Edwin Yeo <edwinye...@gmail.com> > wrote: > > > >> Thank you for your suggestions. > >> Will try that out and update on the results again. > >> > >> Regards, > >> Edwin > >> > >> > >> On 3 June 2015 at 21:13, Alessandro Benedetti < > benedetti.ale...@gmail.com> > >> wrote: > >> > >>> I can see a lot of confusion in the configuration! > >>> > >>> Few suggestions : > >>> - read carefully the document and try to apply the suggesting guidance > >>> - currently there is no need to use spellcheck for suggestions, now > they > >>> are separated things > >>> - i see text used to derive suggestions, I would prefer there to see > the > >>> copy field specifically used to contain the interesting fields > >>> - Yes you need to build the suggester the first time to see suggestions > >>> - Yes , if you add a copy field yo need to re-index to see it filled ! > >>> > >>> Cheers > >>> > >>> 2015-06-03 11:07 GMT+01:00 Zheng Lin Edwin Yeo <edwinye...@gmail.com>: > >>> > >>> > This is my suggester configuration: > >>> > > >>> > <searchComponent class="solr.SpellCheckComponent" name="suggest"> > >>> > <lst name="spellchecker"> > >>> > <str name="name">suggest</str> > >>> > <str > >>> > name="classname">org.apache.solr.spelling.suggest.Suggester</str> > >>> > <str > >>> > > >>> > > >>> > name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookupFactory</str> > >>> > <str name="field">text</str> <!-- the indexed field to derive > >>> > suggestions from --> > >>> > <float name="threshold">0.005</float> > >>> > <str name="buildOnCommit">true</str> > >>> > </lst> > >>> > </searchComponent> > >>> > <requestHandler > >>> class="org.apache.solr.handler.component.SearchHandler" > >>> > name="/suggest"> > >>> > <lst name="defaults"> > >>> > <str name="echoParams">explicit</str> > >>> > <str name="defType">edismax</str> > >>> > <int name="rows">10</int> > >>> > <str name="wt">json</str> > >>> > <str name="indent">true</str> > >>> > <str name="df">text</str> > >>> > > >>> > <str name="spellcheck">true</str> > >>> > <str name="spellcheck.dictionary">suggest</str> > >>> > <str name="spellcheck.onlyMorePopular">true</str> > >>> > <str name="spellcheck.count">5</str> > >>> > <str name="spellcheck.collate">true</str> > >>> > </lst> > >>> > <arr name="components"> > >>> > <str>suggest</str> > >>> > </arr> > >>> > </requestHandler> > >>> > > >>> > > >>> > Yes, I've read the guide.
