Wrong spell-check suggestions by Solr

阅读更多关于 Wrong spell-check suggestions by Solr

问题 Working on Spell Suggest with Solr 4.1. We configured it correctly and Solr offers term as well as collate suggestions. However, we noticed that many times the suggested word / collate doesn't have any results if we search it again. For example, we searched for term " confort " and got no results, with two suggestions " comfort " and " convert ". The first term contains the result.. however the second term doesn't bring any result, and instead suggested two more terms, so term "convert"

SOLR autoCommit vs autoSoftCommit

阅读更多关于 SOLR autoCommit vs autoSoftCommit

I'm very confused about and . Here is what I understand autoSoftCommit - after a autoSoftCommit, if the the SOLR server goes down, the autoSoftCommit documents will be lost. autoCommit - does a hard commit to the disk and make sure all the autoSoftCommit commits are written to disk and commits any other document. My following configuration seems to be only with with autoSoftCommit. autoCommit on its own does not seems to be doing any commits. Is there something I am missing ? <updateHandler class="solr.DirectUpdateHandler2"> <updateLog> <str name="dir">${solr.ulog.dir:}</str> </updateLog>

阅读更多关于 Solr Text field and String field - different search behaviour

问题 I am working on Solr 4+. I have several fields into my solr schema with different solr field types. Does the search on text field and string field differs? Because I am trying to search on string field (which is a copy field of few facet fields) which does not work as expected. The destination string field is indexed and stored both.
