field range (min and max term)
Hi Solr users, Is there a method of retrieving a field range i.e. the min and max values of that fields term enum. For example I would like to know the first and last date entry of N documents. Regards, -Ben
lowercase text/strings to be used in list box
I have a field which will only contain several values (that include spaces). I want to display a list box with all possible values by browsing the lucene terms. I have setup a field in the schema.xml file. I also tried; This allows me to browse all the values no problem, but when it comes to search the documents I have to use the lucene org.apache.lucene.analysis.KeywordAnalyzer, when I would rather use the org.apache.lucene.analysis.standard.StandardAnalyzer and the power of the default query parser to perform a phrase query such as my_field:(the value) or my_field:"the value", which don't work? So is there a way to prevent tokenisation of a field using the StandardAnalyzer, without implementing your own TokenizerFactory? Regards Ben
RE: lowercase text/strings to be used in list box
sorry - this should have been posted on the Lucene user list. ...the solution is to use the lucene PerFieldAnalyzerWrapper and add the field with the KeywordAnalyzer then pass the PerFieldAnalyzerWrapper to the QueryParser. -Ben > -Original Message- > From: Ben Incani [mailto:[EMAIL PROTECTED] > Sent: Friday, 19 October 2007 5:52 PM > To: solr-user@lucene.apache.org > Subject: lowercase text/strings to be used in list box > > I have a field which will only contain several values (that > include spaces). > > I want to display a list box with all possible values by > browsing the lucene terms. > > I have setup a field in the schema.xml file. > > > > > > > > > I also tried; > > > > > > > > > > This allows me to browse all the values no problem, but when > it comes to search the documents I have to use the lucene > org.apache.lucene.analysis.KeywordAnalyzer, when I would > rather use the > org.apache.lucene.analysis.standard.StandardAnalyzer and the > power of the default query parser to perform a phrase query > such as my_field:(the > value) or my_field:"the value", which don't work? > > So is there a way to prevent tokenisation of a field using > the StandardAnalyzer, without implementing your own TokenizerFactory? > > Regards > > Ben >

Hi Yonik,
I have converted to using the Solr search interface and I am trying to
retrieve documents from a list of search results (where previously I had
used the doc id directly from the lucene query results) and the solr id
I have got currently indexed is unfortunately configured not be unique!
I do realise that lucene internal ids are transient, but for a read-only
requests (that are not cached) should be ok.
i have hacked org.apache.solr.request.XMLWriter.writeDoc to do a
writeInt("docId", docId).
code snippet
SolrServer server = new CommonsHttpSolrServer(solrURL);
Map params = new HashMap();
params.put("q", searchQuery);
params.put("rows", "20");
MapSolrParams solrParams = new MapSolrParams(params);
QueryResponse response = server.query(solrParams);
SolrDocumentList docs = response.getResults();
ArrayList hitsList = new ArrayList();
for (int i = 0; i < docs.getNumFound(); i++) {
HashMap resultMap = new HashMap();
SolrDocument doc = (SolrDocument)docs.get(i);
resultMap.put("id", doc.getFieldValue("docId"));
for(int j=0; j
solr web admin
why does the web admin append "core=null" to all the requests? e.g. admin/get-file.jsp?core=null&file=schema.xml
base64 support & containers
Hi Solr users, Does Solr support/or will in the future base64 encoded XML documents so that binary blobs can be added to the index? I have been using this solr client by Darren Vengroff successfully. It easily plugs-in into the Solr package and could also use binary functions in org.apache.solr.util.XML http://issues.apache.org/jira/browse/SOLR-20 So far I have been storing binary data in the lucene index, I realise this is not an optimal solution, but so far I have not found a java container system to manage documents. Can anyone recommend one? Regards, Ben

One of the fields in the add request would contain the original binary document encoded in base64, then this would preferably be decoded to binary and placed into a lucene binary field, which would need to be defined in Solr. Thanks Ben
separate log files
Hi Solr users,
I'm running multiple instances of Solr, which all using the same war
file to load from.
Below is an example of the servlet context file used for each
application.
Hence each application is using the same
WEB-INF/classes/logging.properties file to configure logging.
I would like to each instance to log to separate log files such as;
app1-solr.-mm-dd.log
app2-solr.-mm-dd.log
...
Is there an easy way to append the context path to
org.apache.juli.FileHandler.prefix
E.g.
org.apache.juli.FileHandler.prefix = ${catalina.context}-solr.
Or would this require a code change?
Regards

detecting duplicates using the field type 'text'
Hi Solr users, I have the following fields set in my 'schema.xml'. *** schema.xml *** ... id document_title *** schema.xml *** When I add a document with a duplicate title, it gets duplicated (not sure why) duplicate duplicate When I add a document with a duplicate title (numeric only), it does not get duplicated 123 123 I can ensure duplicates DO NOT get added when using the field type 'string'. And I can also ensure that they DO get added when using . Why is there a disparity detecting duplicates when using the field type 'text'? Is this merely a documentation issue or have I missed something here... Regards, Ben
