full-text-search

问题 I'm basically trying to create a search to find articles (or articles from an author).

问题 I'm using FULLTEXT natural language search, and I notice that it automatically sorts my results by relevance. However, when I start to add things to ORDER, it seems to no longer sort by relevance.

问题 I was creating an application in which we have to store files in data base. So i have chosen varbinary for it. Now we need to configure Full Text Search on this column. But I am able to understand how varbinary data type will handle FTS. Because FTS works on text data type. 回答1: Check this document and this document in MSDN To create a full-text index on a varbinary(max) column, the Full-Text Engine needs access to the file extensions of the documents in the varbinary(max) column. This
