Thankyou Ahmet. You were right.
artist_s:Dora is bringing results.
But I need artist_s:Dora the explorer to bring only those
results which contain Dora the explorer.
I tried to give artist_s:Dora the explorer (phrase
search).. that is working. But artist_s:Dora the explorer is
not working. Any way to make this artist_s:Dora the explorer
to return results that contain this in them.
I learned this from Chris Hostetter's message[1] You can use
q={!field f=artist_s}Dora the explorer
instead of q=artist_s:Dora the explorer.

RE: Excluding field from the results
If description is your field name(say), then you could declare description in your schema.xml as non stored by specifying stored=false in the field declaration as in field name=description stored=false Manas From: Jean-Sebastien Vachon [mailto:js.vac...@videotron.ca] Sent: Fri 3/26/2010 1:51 PM To: solr-user@lucene.apache.org Subject: Excluding field from the results Hi, Is there an easy way to prevent a field from being returned in the response? we can use fl=field1, field2, field3, ... but then our software has an option that must trigger the presence or not of a field in the response. So what I'd like to do is tell Solr to return all fields except one. Does Solr support this? I imagine the syntax could look like this: fl=*, -description Since this is not working, is there any other way of doing this? Otherwise, I will have to manage multiple list of fields. Thanks
Perfect Match
Hello Experts, I need help on one of my issues with perfect matching of terms. I have a collection of artists which are stored in the index against the field name artist_t which is a text type field. This field consists of values like [dora, Dora The Explorer, Princess Dora The explorer] across various docs as in doc field name=artist_tDora/field /doc doc field name=artist_tDora The Explorer/field /doc doc field name=artist_tPrincess Dora The Explorer/field /doc I am searching specifically on artist_t like q=artist_t:Dora. What I need is the one document which matches exactly with Dora, ie. the first doc. Dora the Explorer and Princess Dora The Explorer should not come along with it. But I am getting all the above. To tackle this problem, I tried to copyfield this artist_t to a new field called artist_s which is of type string and indexed the content again. But this approach also doesnt help. I tried to create a new field type with Keyword Tokenizer. and tried to create a field of that type and copied artist_t to this field. That also doesnt work. Is there any way of doing this?? I need exact match ie. if I search for artist_t:Dora The Explorer, I should get only the second doc and not the third one(Princess Dora The Explorer). Please Help!! Manas

RE: XML data in solr field
Thankyou Tommy. But the real problem here is that the xml is dynamic and the element names will be different in different docs which means that there will be a lot of field names to be added in schema if I were to index those xml nodes separately. Is it possible to have nested indexing (xml within xml) in solr without the overhead of adding all those inner xml nodes as actual fields in solr schema?

How to retrieve unique values in typeahead
Hi experts, Please help me out on this. I have a collection of about 30K documents which pertain to pop artists (eg. Madonna, Michael Jackson). These artist names are indexed in the field named artist_t which has the following properties in dynamic field declaration: dynamicField name=*_t type=text indexed=true stored=true/ Most of the documents will have MJ as their artist. I am using EdgeNGram filter factory to get a typeahead implementation. i.e. when I type in m I would get madonna, michael jackson, miley cyrus etc as results. The problem that I have now is that all these terms are repeated. When I search for m, instead of madonna, michael jackson I am getting MJ repeated many times in the initiall 10 docs that solr brings by default. I need to make all these artists unique i.e if I search m, I should get individual results just once? How should I change the schema file and is there a query tweaking required? Any help would be dearly appreciated. Thanks and regards, Manas
Auto Suggest with multiple space separated words
Hi Experts, I need an auto suggest functionality using SOLR which gives me the feel of using the fire fox browser. In short, if I type in a prefix, the results should drop down even if the prefix is not the starting of the drop down items. Example: If I search for Lin, then the results could be [Abe Lincoln, Lindsay Lohan, Sarah Palin, Gasoline .]. Please suggest the best approach. Any help is greatly appreciated. Thankyou, Manas Nair
RE: Multi word synonym problem
Hi, I tried using the recommended approach but to no benefit. The multiword synonyms are still not appearing in the result. My schema.xml has the following fieldType: fieldType name=text class=solr.TextField positionIncrementGap=100 analyzer type=index tokenizer class=solr.WhitespaceTokenizerFactory/ filter class=solr.SynonymFilterFactory synonyms=synonyms.txt ignoreCase=true expand=true/ filter class=solr.StopFilterFactory ignoreCase=true words=stopwords.txt/ filter class=solr.WordDelimiterFilterFactory generateWordParts=1 generateNumberParts=1 catenateWords=1 catenateNumbers=1 catenateAll=0 splitOnCaseChange=0/ filter class=solr.LowerCaseFilterFactory/ !--filter class=solr.EnglishPorterFilterFactory protected=protwords.txt/ -- filter class=solr.RemoveDuplicatesTokenFilterFactory/ /analyzer analyzer type=query tokenizer class=solr.WhitespaceTokenizerFactory/ filter class=solr.SynonymFilterFactory synonyms=synonyms.txt ignoreCase=true expand=false/ filter class=solr.StopFilterFactory ignoreCase=true words=stopwords.txt/ filter class=solr.WordDelimiterFilterFactory generateWordParts=1 generateNumberParts=1 catenateWords=0 catenateNumbers=0 catenateAll=0 splitOnCaseChange=0/ filter class=solr.LowerCaseFilterFactory/ !--filter class=solr.EnglishPorterFilterFactory protected=protwords.txt/ -- filter class=solr.RemoveDuplicatesTokenFilterFactory/ /analyzer /fieldType This text field is the defaultSearchField too. If I give the synonym for Micheal Jackson as Michael Jackson, i.e. in my synonyms.txt file, he entry is: Micheal Jackson = Michael Jackson The response is not searching for Michael Jackson. Instead it is searching for (text:Micheal and text: Jackson).To monitor the parsed query, i turned on debugQuery, but in the present case, the parsed query string was searching Micheal and Jackson separately. I was able to somehow bring the corret response by modifying the synonyms.txt file. I changed the entry as: Micheal Jackson , Michael Jackson (replaced '=' with ','). Is there something that needs to be done with the schema part that has been mentioned above. I would want the synonyms to work when I map them using =. Kindly help.
