If your repository has Xapian search enabled for "Simple Search" (e.g. Then you can make use of the Xapian search syntax to make more complex queries, which needing to use advanced search. This may be useful if you have another website you wish to search your EPrints repository with a specific filter on the results returned (e.g. only results for a particular faculty of department).

Specific Phrases

If you want to search for a specific phrase then ensure the whole phrase is within quote marks, e.g :

"supply change management"

Some words but not others

If you prepend the words you want to find with a + and the words you do not want to find with a '-. E.g.

+science -engineering +mathematics

This word near another word

If you put the phrase NEAR between the two words then it will find matches where the words have 10 or less words in between:

science NEAR mathematics

If you want to find two words that are near or further apart then you can add /n (where n is a number or words between the two words):

science NEAR/3 mathematics

science NEAR/15 mathematics

More complex queries =

You can combine the above three features in various ways:
