Unless quotation marks are used while searching for an exact phrase, all words shorter than three characters are ignored.

If you simply input a few words into the search box and hit the return key, you will end up with a list of every page that contains any one of those words.

But if you want pages which contain BOTH of those words, enter them in the search box separated with the word AND in captial letters. The capital letters are important, or the word will not be recognized as an operand. Example:

Christianity AND Jewish AND effeminate

Typing this in the search box produces a list of only three articles, since only three articles ar Christogenea contain all three of those words.

But if one is searching for a particular phrase, put the phrase in quotation marks. Otherwise, a list of every article containing any of the words in the phrase will result, and that may contain hundreds of choices. Example:

"You are of your father the devil"

Typing this in the search box as it is, with quotation marks, produces a list of only five articles in which that exact phrase appears. Another example:

You are of your father the devil

Typing the same phrase without the quotation marks results in a list of 40 pages, 10 results to a page. Good luck finding what you want in that! But the behavior is uncertain, because the word devil by itself produces about 51 pasges of results.

Using the AND operand for multiple words, or quotation marks for phrases, is a far better way to refine searches.

Hint: a double ampersand && works the same way as AND
