matching word parts

does a search for "foo" also return "foobar" results

[Dice]

Hello Board,
A problem that has boggled me for some time now, when you search for "foo" and look at the cached version of a result, google highlights all instances of "foo" but not of "foobar". Does google practice word-part matching, and if so, will pages containing only "foobar" ever show up in queries for "foo"?

Another question based on the problem above has to do with singular and plural words, if I have a high keyword-density for a singular version of a word (lets assume that "foo" is the singular version of "foobar") will queries for the plural version spit up my site in the SERPS and vice versa, or am I better off using both singular and plural versions of my keyword to maximize google coverage?

TIA,
Dice

Yes to some extent... as per what I have seen firstly they will display the search result only for FOO if you search for FOO but then if they have very less results with the keyword they will also add FOOBAR in result mainly where i have seen teh diffrence is in directory structure if your directory name is www.mydomain.com/foobar/ as being the key in the domain url it will highlight the FOO keyword and if it also found the key in your Key Title and in content area it will surly bring you up in the result page

Hope this may solve your query..
