Filters posts syndicated through FeedWordPress by keywords.
It is not disabled out of the box and you should add keywords by clicking the Add a new keyword filter. You can add as many keyword filters as you want using one or all of the logics [OR, AND, or NOT]
You can add keywords for individual feeds as well. When you select Posts under individual feeds on the Syndication menu of FeedWordPress, you'll have the same options to add keywords.
Keywords are not case sensitive. Enter comma seperated list of words along with your selection of logics.
Do not leave extra space between words - unless you want it. The exact spacing will be matched.
