问题 In elastic search I have a field that is analyzed and I am also storing the original value. I want to search the field with the stored value not the analyzed value. Is there any way to do it? note: I cannot make the field not_analyzed , because I am searching the analyzed values also. 回答1: Take a look at the multi fields type, which will allow to two store the field both analyzed for full text search and not_analyzed for exact matches. 来源： https://stackoverflow.com/questions/24156132/search-a

问题 I'm using Solr 1.4.1 and I'm willing to use TermsComponent for AutoComplete. The problem is, I can't get it to match strings with spaces in them. So to say, terms.fl=name&terms.lower=david&terms.prefix=david&terms.lower.incl=false&indent=true&wt=json matches all strings starting with "david" but if I change it to: terms.fl=name&terms.lower=david%20&terms.prefix=david%20&terms.lower.incl=false&indent=true&wt=json it doesn't match all strings starting with "david ". Is it meant to be that way?

问题 this seems a common problem, except I have had no trouble with this before and the usual fix does not work. It is probably something silly, but I can not find it. I want to index a yammer site as the yammer api is not fast enough for my purpose, problem is that when I try to update my index using the updateDocument functionality the old ones are not deleted. But I have a stored unique key that is not analysed. Here is the relevant code: Document newdoc = new Document(); newdoc.add(new Field

问题 I would like to find "Bug reports" with Lucene using a regular expression, but whenever I try it doesn't work. I used the code from the Lucene page to avoid a bad setup.

问题 I am trying to search for fairly complex queries with Lucene.Net like "inject* needle*" OR "point* thingy"~2 So basically I need wildcards in regular as well as proximity phrases. However, the basic Lucene.Net QueryParser gets rid of these wildcards. I understand that ComplexPhraseQueryParser would work for that, unfortunately this is not included in Lucene.Net. Is there any way of constructing queries like this in Lucene.Net? 回答1: I ended up by actually porting the ComplexPhraseQueryParser

问题 I am using Lucene.Net (version 2.9.4.1) to implement a simple search module.
