Match part of cell to any value in range

I'm working on matching a set of search queries to identified keywords I am tracking. Here is an example:

	A	B	C
1	query		Keyword
2	policy		policy
3	policy and procedure		guideline
4	sick pay guidelines		agenda
5	calendar		brochure
6	medical leave		calendar

Column A contains the search query. Column C contains the list of keywords. I'm trying to find a formula for column B that will match any part of cell A3 to any cell in C and then tell me what the value of C is. For example I would like cell B2 to read "Policy", B3 to read "policy", likewise B4 should read "guidelines". I'm very close with an Index Match formula, but I can only get it to match the first word and then it goes to the closest value in column C. I say I would like a formula, but a VB script would be ok too (very novice at visual basic though).

Thanks for the formula and the welcome, FDibbins! That one works for relating it from C to A. I have some instances where the value in C might match other options in A as well. For the example above, A2 and A3 both have the word "policy" in them and should be tagged as "policy" (or match cell 1 in the range) in the B column. When I applied the formula, it indicated the keyword "policy" matched cell 1 of the query column, when it really needed to match 1 and 2 (and possibly more past row 6).
