Do SOLr index size decrease after deleting documents?

由 我的未来我决定 提交于 2019-12-31 03:22:24
问题 I have a SOLr instance where i index a large number of documents from my client so users can search them in a web application. Because we have a large number of files and they need to search the recent ones only (90 days or so) we have a scheduled job that remove old documents from index. The problem is, the disk space is increasing about 2Gb a day, even with the deletions. Is this a normal behavior or should we do something more to keep index in a stable size? We are using a Java application

Enable CORS for tomcat applications with credentials support

由 和自甴很熟 提交于 2019-12-30 09:59:10
问题 I have a simple GWT application running from IIS on my server. I am trying to test HTTP requests to tomcat running on the same server. However, since both the application servers are running on different ports, my browser (chrome and firefox) treats the requests as a CORS request. To enable tomcat to accept CORS request, I updated it to Tomcat 7.0.52 and enabled the CORS filter in the global web.xml configuration. I tested this simple setup and it seems to work. Here is the code in GWT:

Is there a size or term limit for a Solr query string when using HTTP POST?

由 时光总嘲笑我的痴心妄想 提交于 2019-12-30 05:56:26
问题 I'm using Java to query a Solr server for results that have IDs within a set of known IDs that I am interested in. The best way I could think to get just these results that I am interested in was to create a long query string that looks something like this: q=(item_id:XXX33-3333 OR item_id:YYY42-3445 OR item_id:JFDE-3838) I generate this String, queryString , before making my request, and there are over 1500 such ids included in the request I would eventually like to make. I am using an HTTP

问题 I have a very simple SQL table that I want to import into Solr but because of the features I want for search I can't determine the best schema.

Table ex) id | name ---------------- 1 | boating magazines 2 | boats weekly 3 | boaters collection 4 | shipping lane 5 | ships today Search and expected return ex)
