Keyword search

Run the Keyword search

To run a simple keyword search:

1. From Other Searches, select the Keyword Search option in the Titles domain.
2. Enter one or more keywords and press Enter. You should enter your keywords as normal short phrases, e.g. ”british butterflies moths of great britain”, or just as a series of words.
3. OLIB searches the database and displays a list of items containing the keywords you entered.

Advantages

The keyword search is a powerful tool with a number of advantages:

• Allows text retrieval functions such as phrase searching and proximity searching.
• Gives a wide choice and range of fields to be indexed.
• The index is created in real time for new titles and updated in real time for changed and deleted titles.
• Simple or ‘free-text’ searches can be entered. The search is not case sensitive and you do not need to enter link words such as and. The words can be entered in any order. Free-text searches are stemmed, e.g. computers will retrieve computer, computing and computers.
• Phrase searches are not stemmed, however, this can be over-ridden by inserting a $ symbol at the beginning of the sought term, i.e. “computer $graphic” will retrieve both computer graphics and computer graphic.
• It is possible to use wildcards - % - which will retrieve any number of characters.
• Stop words, such as in, of, the, will be ignored in keyword searches unless they are part of a phrase.
• You can optionally search using either ISBN or EAN and OLIB will automatically convert

Boolean Operators

The Boolean search operators AND, OR and NOT can be used. These are not case sensitive and can also be entered as symbols:
