solr

问题 I am trying to setup a Solr index for searching against a database of product information. For this purpose, I have populated a database of product details and used Solr 6.0.0. For a given product detail (title, brand, other keywords), I would like to know if there is a product in the database that closely matches the given details. I have started dataimport and created the index. However, when I search, the scores of the matching product are all the same in spite of the products listed being

问题 I am trying to do a delta import via the DIH in Solr. When I tried to do it I get this in my effort log: INFO: Starting Delta Import Nov 18, 2012 12:48:46 PM org.apache.solr.core.SolrCore execute INFO: [] webapp=/solr path=/dataimport params={clean=false&command=delta-import} status=0 QTime=1 Nov 18, 2012 12:48:46 PM org.apache.solr.handler.dataimport.SimplePropertiesWriter readIndexerProperties WARNING: Unable to read: dataimport.properties Nov 18, 2012 12:48:46 PM org.apache.solr.handler

问题 I am trying to perform a solr query with multiple query fields including a not equals operator. Example query: field1:abc OR -field2:def The problem is the query returns results for an AND operation instead of an OR , as if the query was: field1:abc AND -field2.def Both queries always return the same result. What is the correct syntax to achieve a correct OR result? I am currently using solr 3.5. Thanks 回答1: Maybe try the following: field1:abc OR (*:* -field2:def) 回答2: for field1:abc OR

问题 Recently my team is using hbase-indexer on CDH for indexing hbase table column to solr . When we deploy hbase-indexer server (which is called Key-Value Store Indexer) and begin testing. We found a situation that the rows size between hbase table and solr index is different : We used Phoenix to count hbase table rows: 0: jdbc:phoenix:slave1,slave2,slave3:2181> SELECT /*+ NO_INDEX */ COUNT(1) FROM C_PICRECORD; +------------------------------------------+ | COUNT(1) | +--------------------------

问题 In the configuration file solrconfig.xml , is there a parameter to adjust tolerance in order to have multiple suggestions even if the number of different letters between the query & the suggestion is large? In my solrconfig.xml suggestion configuration, I have : The spellcheck search component : <lst name="spellchecker"> <str name="name">default</str> <str name="field">title</str> <str name="classname">solr.DirectSolrSpellChecker</str> <!-- the spellcheck distance measure used, the default is

问题 I have a schema which includes a maximum radius for a result to show up - for example, 50. I am able to calculate distance and filter by that without problem, but I really need to filter by that field, which changes from document to document. I've tried: fq={!frange l=0 u=radius_field}geodist() and fq={!func}geodist():[0 TO radius_field] to no effect. Is there any way to do this? I could filter client-side, worst case, but I figure there's somebody out there who has had the same use case. 回答1

问题 as far as I know this is not possible as the solr wiki. do you guys have any work around? 回答1: The only workaround is to set the rows value large enough to return all documents. However, I wouldn't recommend this for anything larger than about 1000 documents. If the number of documents you are fetching is large enough, you will run into memory or timeout issues with the XML you have to generate and parse. For example, if there are 2-3 million documents in your index, do you really want all of

问题 Is it possible to know the indexing time of a document in solr. Like there is a implicit field for "score" which automatically gets added to a document, is there a field that stores value of indexing time? I need it to know the date when a document got indexed. Thanks 回答1: Solr does not automatically add a create date to documents. You could certainly index one with the document though, using Solr's DateField. In earlier versions or Solr ( < 4.2 ), there was a commented timestamp field in the
