Re: Remove the deleted docs from the Solr Index
Hi Shalin: I get your point about not knowing what has been deleted from the database. So this is what even I am looking for: 0) A document (id=100) is currently part of solr index.( 1) Lets say the application deleted a record with id=100 from database. 2) Now I need to execute some DIH command to say remove document where id=100. I dont expect the DIH to automatically detect what has been deleted, but I am looking for a DIH command/special-command to request deletion from index. Is that possible ? also as an alternate solution, is it possible to build index using DIH, and use the solr.XmlUpdateRequestHandler request handler to delete/update these one off documents ? Is this something you will recommend ? Thanks, ~Ravi Gidwani. On Tue, Dec 29, 2009 at 3:03 AM, Mohamed Parvez par...@gmail.com wrote: I have looked in the that thread earlier.

Limiting Solr queries to predefined Values
Hi there! Is it possible, to limit the Solr Queries to predefined values e.g.: If the User enters /select?q=anywordfq=anyfilterrows=13 then the filter and rows arguments are ignored an overwritten by the predefined values specialfilter and 6. The goal is to prevent users from getting particular information (e.g. very big fields to control bandwidth) sent to their browser. Maybe it could be done by blocking the access to the /select-path using resin (if it used regex to discribe url-pattern).

Yes, you can set up the request handler mapping with an invariant (instead of defaults) section with those parameters specified in solrconfig.xml. However, with fq, you may want to put that in an appends section instead, so that other filters can be specified from the client as well. Erik
how to do a Parent/Child Mapping using entities
Hello everybody, i would like to know how to create index supporting a parent/child mapping and then querying the child to get the results. in other words; imagine that we have a database containing 2 tables:Keyword[id(int), value(string)] and Result[id(int), res_url(text), res_text(tex), res_date(date), res_rank(int)] For indexing, i used the DataImportHandler to import data and it works well, and my query response seems good:(q=*:*) (imagine that we have only this to keywords and their results) ?xml version=1.0 encoding=UTF-8 ? - response - lst name=responseHeader int name=status0/int int name=QTime0/int - lst name=params str name=q*:*/str /lst /lst - result name=response numFound=2 start=0 - doc str name=id1/str str name=keywordKey1/str - arr name=res_url strurl1/str strurl2/str strurl3/str strurl4/str /arr - arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc - doc str name=id2/str str name=keywordKey2/str - arr name=res_url strurl1/str strurl5/str strurl8/str strurl7/str /arr - arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc /result /response but the problem is when i tape a query kind of this:q=res_url:url2 AND res_rank:1 and this to say that i want to search for the keywords in which the url (url2) is ranked at the first position, i have a result like this: ?xml version=1.0 encoding=UTF-8 ? - response - lst name=responseHeader int name=status0/int int name=QTime0/int - lst name=params str name=qres_url:url2 AND res_rank:1/str /lst /lst - result name=response numFound=1 start=0 - doc str name=id1/str str name=keywordKey1/str - arr name=res_url strurl1/str strurl2/str strurl3/str strurl4/str /arr - arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc /result /response But this is not true; because the url present in the 1st position in the results of the keyword key1 is url1 and not url2. So what i want to say is : is there any solution to make the values of the multivalued fields linked; so in our case we can see that the previous result say that: - url1 is present in 1st position of key1 results - url2 is present in 2nd position of key1 results - url3 is present in 3rd position of key1 results - url4 is present in 4th position of key1 results and i would like that solr consider this when executing queries.

performance question
Greetings! Is there any significant negative performance impact of using a dynamicField? Likewise for multivalued fields? The reason why I ask is that our system basically aggregates data from many disparate data sources (structured, unstructured, and semi-structured), and the management of the schema.xml has become unwieldy; i.e. we currently have dozens of fields which grows every time we add a new data source. I was considering redefining the domain model outside of Solr which would be used to generate the fields for the indexing process and the metadata (e.g. display names) for the search process. Thoughts? -- A. Steven Anderson Independent Consultant st...@asanderson.com

Re: how to do a Parent/Child Mapping using entities
Hi, you could create an additional index field res_ranked_url that contains the concatenated value of an url and its corresponding rank, e.g., res_rank + + res_url Then, q=res_ranked_url:1 url1 retrieves all documents with url1 as the first url. A drawback of this workaround is that you have to use a phrase query thus preventing wildcard searches for urls. -Sascha Hello everybody, i would like to know how to create index supporting a parent/child mapping and then querying the child to get the results. in other words; imagine that we have a database containing 2 tables:Keyword[id(int), value(string)] and Result[id(int), res_url(text), res_text(tex), res_date(date), res_rank(int)] For indexing, i used the DataImportHandler to import data and it works well, and my query response seems good:(q=*:*) (imagine that we have only this to keywords and their results) ?xml version=1.0 encoding=UTF-8 ? -response -lst name=responseHeader int name=status0/int int name=QTime0/int -lst name=params str name=q*:*/str /lst /lst -result name=response numFound=2 start=0 -doc str name=id1/str str name=keywordKey1/str -arr name=res_url strurl1/str strurl2/str strurl3/str strurl4/str /arr -arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc -doc str name=id2/str str name=keywordKey2/str -arr name=res_url strurl1/str strurl5/str strurl8/str strurl7/str /arr -arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc /result /response but the problem is when i tape a query kind of this:q=res_url:url2 AND res_rank:1 and this to say that i want to search for the keywords in which the url (url2) is ranked at the first position, i have a result like this: ?xml version=1.0 encoding=UTF-8 ? -response -lst name=responseHeader int name=status0/int int name=QTime0/int -lst name=params str name=qres_url:url2 AND res_rank:1/str /lst /lst -result name=response numFound=1 start=0 -doc str name=id1/str str name=keywordKey1/str -arr name=res_url strurl1/str strurl2/str strurl3/str strurl4/str /arr -arr name=res_rank str1/str str2/str str3/str str4/str /arr /doc /result /response But this is not true; because the url present in the 1st position in the results of the keyword key1 is url1 and not url2.

Re: Implementing Autocomplete/Query Suggest using Solr
We do auto-complete through prefix searches on shingles. Just to confirm, do you mean using EdgeNgram filter to produce letter ngrams of the tokens in the chosen field? No, I'm talking about prefix search on tokens produced by a ShingleFilter. I did not know about the Prefix query parser in Solr. Thanks a lot for pointing out the same. I find relatively little online material about the Solr/Lucene prefix query parser. Kindly point me to any useful resource that I might be missing. I looked into the Solr/Lucene classes and found the required information. Am summarizing the same for the benefit of those that might refer to this thread in the future. The change I had to make was very simple - make a call to getPrefixQuery instead of getWildcardQuery in my custom-modified Solr dismax query parser class. However, this will make a fairly significant difference in terms of efficiency. The key difference between the lucene WildcardQuery and PrefixQuery lies in their respective term enumerators, specifically in the term comparators. The termCompare method for PrefixQuery is more light-weight than that of WildcardQuery and is essentially an optimization given that a prefix query is nothing but a specialized case of Wildcard query. Also, this is why the lucene query parser automatically creates a PrefixQuery for query terms of the form 'foo*' instead of a WildcardQuery. A big thank you to Shalin for providing valuable guidance and insight. And one final request for Comment to Shalin on this topic - I am guessing you ensured there were no duplicate terms in the field(s) used for autocompletion. For our first version, I am thinking of eliminating the duplicates outside of the results handler that gives suggestions since duplicate suggestions originate only from different document IDs in our system and we do want the list of document IDs matched. Is there a better/different way of doing the same? Regards, Prasanna.

Solr Cell - PDFs plus literal metadata - GET or POST ?
Hi all I'm experimenting with Solr. I've successfully indexed some PDFs and all looks good but now I want to index some PDFs with metadata pulled from another source. I see this example in the docs. curl http://localhost:8983/solr/update/extract?literal.id=doc4captureAttr=truedefaultField=textcapture=divfmap.div=foo_tboost.foo_t=3literal.blah_s=Bah; -F tutori...@tutorial.pdf I can write code to generate a script with those commands substituting my own literal.whatever. My metadata could be up to a couple of KB in size. Is there a way of making the literal a POST variable rather than a GET? Will Solr Cell accept it as a POST? Something doesn't feel right about generating a huge long URL. I think Tomcat can handle up to 8 KB by default so I guess that's okay although I'm not sure how long a Linux command line can reasonably be. I know Curl may not be the right thing to use for production use but this is initially to get some data indexed for test and demo. Thanks Ross

My Application is multiclient, and i need to separate the index by client. In this Scenario, whats the best solution? SOLR or HIbernateSearch I See SOLR is a dedicated server and has a good performance test. I don't see advantages to use hibernate-search in comparison with SOLR (Except the fact of integrate with my Mapped Object) Thanks for Help -- att, ** Márcio Paulino Campo Grande - MS MSN / Gtalk: mcopaul...@gmail.com ICQ: 155897898 **
