linq - How to get the expected correct matching search results? -

code:

public list<searchresult> getrecordsbyterm(string term)         {             return                 _datareadservice.getrecords()                                         .where(x => x.firstname.contains(term) || term.contains(x.firstname)                                                     || x.lastname.contains(term) || term.contains(x.lastname)                                                     || x.emailaddress.contains(term) || term.contains(x.emailaddress))                                                     .select(x => new searchresult()                                                     {                                                         detailedname = (x.firstname ?? string.empty) + " " + (x.lastname ?? string.empty) + (x.title != null && x.title != string.empty ? ", " : string.empty) + (x.title ?? string.empty) + " (" + (x.office ?? string.empty) + ")",                                                         email = x.emailaddress                                                     })                                         .orderby(x => x.detailedname)                                         .tolist();         } 

in above code, if passing term "baske", getting 2 search results follows:

1, "bas ge"  2, "basket" 

"bas ge" should not in search results, getting result. how redefine above code, need exact matching words?

well if "bas" first name, term.contains(x.firstname) true. seems odd thing do.
