Any Algorithm for the below scenarios

 Hi,
I'm working on resume parsing, Now i'm in to keyword searching from a resume to get the word frequency,  now the problem is I have a doc file say it contains (Sql server 2005, Ms sql server, Sql server).... Now if i search for "sqlserver" it should get all this 3 values. See here i try to search without space in "sqlserver"
 
Is there any algorithm already exist for this kinda scenarios or If you guys have any of algorithm?
 
TIA
