full-text-indexing

问题 I'm getting my feet wet with handling a load of Office and PDF documents with SQL Server 2012's FILETABLE feature, and using fulltext search on top of that.

问题 My MySQL table is not returning results with a MATCH (col) AGAINST ('') query. The table is simple: id | url | fullTextIndex And my query is SELECT *, Match(fullTextIndex) AGAINST ("7f7f7f807f8080807f8080807f7f7f807c828888808a86967e8b858d7f89838a76829e958f7badb68084a3a38384899077848b877f799f9c85799fa2827d8c8a ") FROM Pictures; The last column, the match, is always 0. Except, I know for a fact that the string above is contained, verbatim, in one of the values. Things to note: The string is
