Forms :: Search Form Did Not Return All Data Records For That Particular Result Set

All using access 2010. Here's the situation. I built a searchform according to datapigtechnologies video. Used a query with criterias on fields i want to search on the form: ex.

Code:
Like [frm]![frmMyform]![MyField]

It worked fine i thought until i ran the same query outside the form without the criteria field. I filtered the query for the same result and the one used on the search form did not return all data records for that particular result set. Ex. on the searchform; I select the fields I wanted to filter then ran the query. I come up with only 9 records when it should be 18 I get with running the exact same query without the criteria and manually filter the results.
