SQL Server 2008“包含”搜索搜索数值是否返回具有相同长度的不同编号的所有记录？

Question

I have a search where users can enter any value, sometimes these are legitimately just numeric. When searching for

Select * FROM Updates WHERE contains(Remarks, '"10010234331"')

it will return unrelated results that have numbers in of the same length, ie one match for the above is

"PO input differently on orders, refs are: 

1001024894 
10010248940"

As you can see, the search is not a substring of either of these. Any ideas how to tell it to not just guess?

Answer 1

Right.

As unbelievable as this sounds, it turns out that if the full-text index "language for word-breaker" is set to anything other than "English", the full-text index will only index the first 5 numbers of a number string. This means that the above is returning as a match because they both start "10010".

"French, "German", "Hebrew", even "Neutral" was returning incorrect results, only "English" returns only matches for the whole string.
