SOLR to ignore some terms of a phrase
When working with Solr directly, this is supported. I am not familiar with Solr.NET though, can anyone comment on whether this feature is supported by that client?
Solr 5.1.0: How to set the unique key via Schema API
No its not possible as of now. Its an open feature request. https://issues.apache.org/jira/browse/SOLR-7242
Heap memory Solr and Elasticsearch
Solr heap size must be set according your business. Set -Xms=2G and -Xmx=12G is just a recommendation to lots of popular Solr applications but it's not mandatory. You need to assess your requirements and set the heap to work well for you. I really recommend you to use at least...
Partially indexing Cassandra table with SOLR
solr,cassandra,datastax-enterprise
There is no way to index just a few rows. I agree that a parallel table (probably with TTL) is likely your best bet. Here are some (pretty effective) tactics to minimize the size of your DSE Search index. You can probably shrink it by ~50% if you're not using...
Solr Cloud Managed Resources
solr,solrcloud,synonym,stop-words
In SolrCloud configuration and other files like stopwords, are stored and maintained by Zookeeper. Which means you do not need to individually send updates to each server. Once you have SolrCloud, before putting in any data, you will create a collection. Each collection has its own set of resources/config folder....
Is it possible to index views in Apache Solr
You can use the data import handler and set the "query" to point to your view. See example below: <dataConfig> <dataSource driver="org.hsqldb.jdbcDriver" url="jdbc:hsqldb:/temp/example/ex" user="sa" /> <document name="products"> <entity name="feature" query="SELECT * FROM MyView"> <field column="attr_1" name="Attr1" /> <field column="attr_2" name="Attr2" /> <field column="attr_3" name="Attr3" /> </entity> ...

TYPO3 Solr extension and facets
solr,typo3,typoscript,typo3-6.2.x
I assume that your type-field in the solr index only has 4 values, one for pages, 1 each for the two custom tables, and 1 for news. In order to get 6 facets, you need to have 6 different values in the field the faceting is done on. I'm not...
Using schema.xml with Solr
The problem is that you are referencing a field type booleans that is not defined in your schema.xml file. When you create a core a file managed-schema is created in server\solr\my_collection\conf\. Rename this file to schema.xml and restart solr with ClassicIndexSchemaFactory and it will work fine.
Data import in solr from multiple entities
solr,dataimporthandler,data-import
Finally got a solution. We need to modify data-config.xml file, under which there would be 3 different entities. 2 from MySQL and 1 from Solr core itself. For MySQL, entity should be something like this <entity name="entity name" dataSource="data source created in the file" query="SQL query to retrieve the data"...

How to insert multiple index at a time on a solr update using json

Sunspot/rails configuration for multi-core (for different language docs) Solr 5 in one environment
ruby-on-rails,solr,sunspot-rails
I figure out how to index multilingual documents in a single Solr instance and search the indexed documents by a specified language from sunspot/rails. This method uses different fields instead of cores for different languages, so it is not a direct answer to my question, but a working example to...
How can I sort by realtime score in solr?
The key for this are function queries. Assumed you use EDisMaxQP, you can specify a boost function (bf) with this value: sub(product(answer_count,100),product(div(ms(NOW,created_at),3600000),5)) However, a function query would influence scoring, but it rather looks like you don’t want any scoring at all and instead a fixed sort order, so I guess...

Solr Indexing in Storm topology vs Hbase NG Indexer
After some analysis, we went ahead and implemented the design with NGHbas indexer. One argument is that we cannot gaurantee same data in hbase and solr as we cannot handle transactions at large scale. Also we have similar design for streaming data. So made used of the setup

Understanding Apache Lucene's scoring algorithm

Lucene vs Solr, indexning speed for sampe data
java,indexing,solr,lucene,full-text-search
Solr is a general-purpose highly-configurable search server. The Lucene code in Solr is tuned for general use, not specific use cases. Some tuning is possible in the configuration and the request syntax. Well-tuned Lucene code written for a specific use-case will always outperform Solr. The disadvantage is that you must...

How do I combine Facet and FilterQueries using Spring data Solr?
I assume you're using Spring Data Solr, from your reference to SimpleFacetQuery.

MongoDB Solr search to fetch document relationships in one single search request
The ideal solution of course (from Solr perspective) would be to store the data in Solr in the denormalized form.

How can I maintain the row mapping after sorting on facets? If I sort on 1 facet, other column values don't get sorted accordingly
Every facet order it's independent of others, so if you store the id and the name in separated fields, you can't assume that both are going to be in the same row. By count it will be the case only if the result number is different for each one. (so...
