Is it possible to ignore noise words conditionally in working with Full text search containstable

Question

I have a question on stoplist file. I need to search for exact phrase string("this is the incident") which contains   noise words. As part of the FT search engine, during parsing it eliminates noise word and search on remaining string in
the given phrase. 
let us say there are 10 rows which contains the term "incident" in the FT table . and 1 row which has the exact phrase.i.e."this is the incident".
if we use containstable() to search for "this is the incident", we are getting 10 rows instead of 1 row.
To resolve the issue, we have 3 solutions
1.either stoplist file needs to be modified to remove the words (this,is,the)
2. set stoplist = OFF.
3.empty stoplist.
Apart from the above solutions, is there any better solution with out touching noise words file list.
If any solution that provides flexibility to ignore noise words conditionally at one time and not to ignore them. 
Please provide your suggestion.

One question that I ask is:  Why would I want to exclude noise words?
Noise words were created to limit the size of the full text indexes and avoid processing the many 'this', 'is', and 'the' common words.  But the disadvantage of doing so is that you cannot find some things as you would like.
My feeling is that computers are more powerful and have more storage and it is often better to just index everything.  As long as your search does not include 'the', then the large number of 'the's in the system will pretty much be ignored. 
NOTE: If you change the noise words, including SET STOPLIST = OFF, you have to rebuild the index in order for it to implement your decision.
Of course, for very, very large full text indexes you would need to test.
Is your full text search on relation database columns, e.g.  Description NVARCHAR(1000)  or are you searching Word, Excel, and other more complex data?
If your full text is relational columns, it might be that you could:
1. Select only the fulltextkey into a temp table (e.g. #FTSfulltextkey) from the full text index using noise words.  That would give you 10 rows.
2. Then directly query the table to find the string as you define above.  (But remember that punctuation and symbols are generally ignored by Full Text Indexing, but would still be there in the string of text.)
SELECT *
FROM MyTextTable T
JOIN #FTSfulltextkey K
ON T.fulltextkey = k.fulltextkey
WHERE T.Description like '%this is the incident%'
Full text search is powerful, but it has limits. And the behaviour changes depending on the Language of the search.
