I'm using SQL Server DB and I would like to write query which will look for a fields with two or more slashes in it, lets say we have these rows:
1. abc/def/g
2. abcd/efg
3. a/b/c/d/e/f/g
So it should return 1st and 3rd row! What is the easiest way to do so?
Thanks in advance!

I come to know that this is used to speed up data retrieval..I like to know more about it .Thanks .
Indexing is a way of sorting a number of records on multiple fields. Creating an index on a field in a table creates another data structure which holds the field value, and pointer to the record it relates to. This index structure is then sorted, allowing Binary Searches to be performed on it.
