PatternTokenizer question

I have defined a comma-delimited pattern tokenizer as follows: <fieldType name="text_comma" class="solr.TextField" positionIncrementGap="100"> <analyzer> <tokenizer class="solr.PatternTokenizerFactory" pattern=","/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldType> <field name="commafld" type="text_comma" indexed="true" stored="true"/> This appears to work fine when adding documents, since if I add a field commafld as "word1,WORD2,word 3" I see terms in the index as expected: "word1", "word2", and "word 3". When I query, I am expecting that the same tokenization would take place, so a query that has 'commafld:(word 3)' would match term "word 3". However, I find I have to submit the query as 'commafld:("word 3")'. That is, it seems as if whitespace tokenization is taking place, not the comma-delimited tokenization. Am I misunderstanding what should be happening or making some basic mistake? Thanks. -- View this message in context: http://old.nabble.com/PatternTokenizer-question-tp26497675p26497675.html Sent from the Solr - User mailing list archive at Nabble.com.

Re: Migrating to Solr

This is really a great source of migration. I guess i will have good questions after trying. But what i know that will be a little harder will be the use of collections (facets in Solr) and hierarquical navigators.

Re: access denied to solr home lib dir

: Check. I even verified that the tomcat user could create the : directory (i.e. "sudo -u tomcat6 mkdir /opt/solr/steve/lib"). Still : solr complains. Note that you have an AccessControlException, not a simple FileNotFoundException ... the error here is coming from File.canRead (when Solr is asking if it has permision to read the file) but your ServletContainer evidently has a security policy in place that prevent's solr from even checking (if the security policy allowed it to check, then it would return true/false based on the actaul file permisions)... http://java.sun.com/j2se/1.4.2/docs/api/java/io/File.html#canRead%28%29 Tests whether the application can read the file denoted by this abstract pathname. Returns: true if and only if the file specified by this abstract pathname exists and can be read by the application; false otherwise Throws: SecurityException - If a security manager exists and its SecurityManager.checkRead(java.lang.String) method denies read access to the file ...note that Tomcat doesn't have any special SecurityManager settings that prevent this by default. something about your tomcat deployment must be specifying specific Security Permision rules. : >> Caused by: java.security.AccessControlException: access denied : >> (java.io.FilePermission /opt/solr/steve/./lib read) : >> Â Â Â at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) : >> Â Â Â at java.security.AccessController.checkPermission(AccessController.java:546) : >> Â Â Â at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) : >> Â Â Â at java.lang.SecurityManager.checkRead(SecurityManager.java:871) : >> Â Â Â at java.io.File.canRead(File.java:689) : >> Â Â Â at org.apache.solr.core.SolrResourceLoader.replaceClassLoader(SolrResourceLoader.java:157) : >> Â Â Â at org.apache.solr.core.SolrResourceLoader.addToClassLoader(SolrResourceLoader.java:128) : >> Â Â Â at org.apache.solr.core.SolrResourceLoader.<init>(SolrResourceLoader.java:97) : >> Â Â Â at org.apache.solr.core.SolrResourceLoader.<init>(SolrResourceLoader.java:195) : >> Â Â Â at org.apache.solr.core.Config.<init>(Config.java:93) : >> Â Â Â at org.apache.solr.servlet.SolrDispatchFilter.<init>(SolrDispatchFilter.java:65) : >> Â Â Â ... 40 more -Hoss

Weighting of synonyms

Howdy, I recently rolled a custom WordNet synonym filter that pulls synonyms from WordNet during indexing. All that is nice and dandy; however, it causes problems in the sorting. Sometimes, the top match will come from a synonym rather than the original word. An example in our system is a search on the word "party". The first match was a doc with the word "company" which, in WordNet, has "party" as a synonym. So the question is: is there a way to weight original word matches more than synonym matches? In other words, I want all docs with "party" in the text to come up first, then docs whose terms have "party" as a synonym. I'm hoping there is a way ;) It would seem this would be a common enough issue. However, from my looking at the source code I fear the worst as I don't see that you can do this unless it would make sense to utilize the "type" field of Token. Thanks, Lajos
