Ways for users to select/filter multiple rows?

I'm looking for some suggestions on how best to allow users to display a selection of rows from a dataset.

Specific questions:

1. Search: is there a way to make the built-in search effectively use 'OR' for separate words? So with a table of fruits, typing 'apple pear banana' in the search box would leave three rows (one per fruit), rather than no results (because there isn't a row with 'apple pear banana' in it.

2. Multiselect->filter: if I enable multiselect on a table, would searching for individual fruits then selecting them persist? I.e. will this work: search 'apple', select, search 'pear' select, search 'banana', select, click 'filter' button that filters the table to just the selected rows?

3. is there a better alternative?
