Re: How to apply Semantic Search in Solr

Does Solr/Lucene collapse Exception of multiple threads?

I have observed slowness of my Solr instance co-occurred with thread stack overflow error, both happened at about the same time: 2014-03-09 03:14:43,166 ERROR SolrDispatchFilter|null:java.lang.RuntimeException: java.lang.StackOverflowError at org.apache.solr.servlet.SolrDispatchFilter.send

Hi, If I go with copy field than will it increase I/O load considering I have RAM less than one third of total index size? Thanks  Abhishek   Original Message   From: Erick Erickson Sent: Monday, 10 March 2014 01:37 To: solr-user@lucene.apache.org Reply To: solr-user@lucene.apache.org Subject: R

Hi, I meant that while searching A AND B should return result individually and when together with a AND.  I want "A B" should not give result. Though A,B is indexed with StandardTokenizer.  Thanks  Abhishek   Original Message   From: Furkan KAMACI Sent: Monday, 10 March 2014 06:11 To: solr-use

RE: SolrCloud setup guidance

Not sure how fast your index will grow but first you may still want to consider upgrading the single machine to 128 GB to see how the performance is coming. Current memory 7 GB is really low. After that you may want to add another node to partition the index into 2 nodes/shards (assuming you ha

Querying XML

I have some XML stored in Solr that looks like this: What I’d like to do is get a hit for this document if there’s an element in the XML where (@name=”Bob” AND @city=”Cincinnati”). If I write something like this, I’ll get a hit – although I’m not actually matching what I’m loo

Re: Optimizing RAM

I'd go for a copyField, keep the stemmed and unstemmed version in the same index. An alternative (and I think there's a JIRA for this if not an outright patch) is implement a "special" filter that, say, puts the original tken in with a special character, say $ at the end, i.e. if indexing "running

Hi Erick, Thanks for replying, I want to index A,B (with or without space with comma) as separate words and also want to return results when A and B searched individually and also "A,B" . Please let me know your views. Let me know if i still havent explained correctly. I will try again. Thanks a

You've contradicted yourself, so it's hard to say. Or I'm mis-reading your messages. bq: During indexing i want to token on all punctuations, so i can use StandardTokenizer, but at search time i want to consider punctuations as part of text, and in your second message: bq: when i search for "A,

Re: Which Tokenizer to use at searching

Hi; Firstly you have to keep in mind that if you don't index punctuation they will not be visible for search. On the other hand you can have different analyzer for index and search. You have to give more detail about your situation. What will be your tokenizer at search time, WhiteSpaceTokenizer?

Which Tokenizer to use at searching

Hi Friends, I am concerned on Tokenizer, my scenario is: During indexing i want to token on all punctuations, so i can use StandardTokenizer, but at search time i want to consider punctuations as part of text, I dont store contents but only indexes. What should i use. Any advices ? -- Thank
