问题 I am using the demo IndexFiles and SearchFiles classes to index and search which are in org.apache.lucene.demo packet. My issue is when I use a query that contains more than a word, I am not getting results that have the exact match. For instance: Enter query: "natural language" Searching for: "natural language" 298 total matching documents 1. download\researchers.uq.edu.au\fields-of-research\natural-language-processing .txt 2. download\researchers.uq.edu.au\research-project\16267.txt 3.

问题 I've seen many of this topics here but still confusing to implement it. In my case i need to do these: Search certain phrases in title & text and give title^3, text^1 based on result in #1, i need to boost the results by modified time i've tried these with different results: /solr/select ?q={!boost b=$dateboost v=$qq defType=dismax} &dateboost=recip(ms(NOW/HOUR,modified),86400000,1,1) &qq=video &qf=title^3+text &pf=title^3+text &debugQuery=true And Normal Query with different setting in

问题 I have just started playing around with Solr and I have it deployed and running on Tomcat. I have the schema and data import handler set up and it indexes the files just fine. Now I want to schedule this dataImportHandler to run every hour or so. There is a wiki page detailing the files here. But there are not instructions on where to create the files and how to deploy them A similar question has been asked on Stack Overflow before here. The answer was to "Create classes ApplicationListener,

问题 I have a list of cities on mysql db which is hooked onto a UI for autocompletion purposes. I am currently using solr-5.3.0. Data import is happening through scheduled delta imports. I have the following questions: I want to implement spell checker to this feature. I tried using: DirectSolrSpellChecker IndexBasedSpellChecker FileBasedSpellChecker Out of these 3 only FileBasedSpellChecker is able to give suggestions that solely exists on db. For eg, while searching cologne I've got results like

问题 I am trying to understand how to use the LUCENE Spatial queries in Orientdb 2.2.17 using pyorient. I have note yet figure it out how to select all the properties of a point vertex class that is within a polygon vertex from another class. Region Vertex Class has two properties: name coordinates (EMBEDDED OPolygon) LUCENE index CREATE CLASS Region EXTENDS V CREATE PROPERTY Region.name IF NOT EXISTS STRING CREATE PROPERTY Region.coordinates IF NOT EXISTS EMBEDDED OPolygon CREATE INDEX Region

问题 I've a problem in Lucene based searching. I have designed a document with five fields. Consider the document be Address with addressline1, addressline2, city, state and pin. If a search is to be performed, then the search has be done in all the fields, so I'm using boolean term queries. So the results would be retrieved. Now I also have to respond not only with responses but also with the matching field. For eg if the city field matches the search, then I should respond as city matches the

问题 I'm using Azure Search based on the rich Lucene Query Parser syntax. I defined to "~1" as additional parameter to one symbol for distance ). But I faced with problem, that the entity is not ordered even if there is exact match. (For example,"blue~1" would return "blues", "blue", "glue". Or when searching product SKU like "P002", I would get result "P003", "P005", "P004", "P002", "P001", "P006" ) So my question: is there some way to define, that the entity with exact match must be first in
