solr

问题 I've a large set of text documents which I will index with Solr, in a format where each line of text has associated metadata. For example: #metadata1 A line of text. #metadata2 Another long, broken line of #metadata3 text that should be searchable. I'd like to index this such that the content is searchable, including phrase matches spanning multiple lines, but not the metadata. However, I can't discard the metadata: I would like to have any matches still have the associated metadata. E.g. A

问题 So I have some cores in one solr server and some cores in another solr server and I need to join them. The schema of the cores are different with no matching attribute name but matching attribute value. I tried to do it with join & shards but both didn't work. Can you help me out? attribute1 is in abc:7892/solr/core1 attribute2 , attribute3 is in xyz:8983/solr/core2 {!join from=attribute1 to=attribute2 fromIndex="xyz:8983/solr/core2"} attribute3:* Error Message : Cross-core join: no such core

问题 I have solr array field that could contain string with some separate words as a one value, for example ["Super Ball", "BlaBla", "Info"]. I need to see all those 3 values as an facet values and have case insensitive search by fields as well.

问题 Edit : SQL doesn't work for this. I just found out about Solr/Sphinx and it seems like the right tool for this problem, so if you know Solr or Sphinx I'm eager to hear from you. Basically, I have a .tsv with patent info and a .csv with product names. I need to match each row of the patents column against the product names and extract the occurrences in a new .csv column. You can scroll down and see the example at the end. Original question: SQL newbie here so bear with me :). I can't figure

问题 Does it make sense to have multiple shards in Elasticsearch if I am going to use only single machine? Will it improve performance in any way? Same question for Apache Solr - does it make sense to use Solr Cloud with ZooKeeper for single server instance or just create one core without any sharding? Let's assume I am not going to use other machines in future, so the main point is how sharding on single machine influence search engines performance? 回答1: There are certain parts of Lucene that's

问题 In a Regex, how to remove all the leading, trailing and where ever spaces exist in SOLR. To remove special characters, we can have the PatternReplaceFilterFactory as <filter class="solr.PatternReplaceFilterFactory" pattern="([^a-z])" replacement="" replace="all" /> What pattern value will be formed to remove the spaces whereever it comes. 回答1: I don't know SOLR but based on your example I guess you could just do <filter class="solr.PatternReplaceFilterFactory" pattern="(\s+)" replacement=""
