- Search is not case sensitive. You do not need to capitalize your search terms, except for Boolean Operators.
- For example, the following two searches are identical:
- Phrase Searches
- Use quotes to search for exact phrases. Example:
- Word Stemming
- Word stems are used by default.
- For example, this search will find items containing work, works, worker or working:
- By default, the exact, non-stemmed versions of words are weighted higher than stemmed versions, so they will appear higher in search results. This works well for most searches.
- To control how stemming works, click Advanced Search and select one of the Stemming options.
- To prevent stemming, click No. This will often give fewer, more exact results.
- Stemming can be completely prevented when searching Title, Author, Subject and Series fields.
- Stemming can be reduced when searching All Fields but cannot be completely prevented.
- To give stemmed and non-stemmed versions equal weight, click Yes.
- Wildcard Searches
To perform a single character wildcard search use the ? symbol.
For example, to search for "text" or "test" you can use the search:
To perform a wildcard search that matches multiple characters (0 or more), use the * symbol.
For example, to search for test, tests or tester, you can use the search:
This may be useful to save typing a long word, or if you do not know the exact spelling of a word.
You can also use the wildcard searches in the middle of a term.
Note: You cannot use a * or ? symbol as the first character of a search.
- Fuzzy Searches
Use the tilde ~ symbol at the end of a Single word Term. For example to search for a term similar in spelling to "roam" use the fuzzy search:
This search will find terms like foam and roams.
An additional parameter can specify the required similarity. The value is between 0 and 1, with a value closer to 1 only terms with a higher similarity will be matched. For example:
The default that is used if the parameter is not given is 0.5.
- Proximity Searches
Use the tilde ~ symbol at the end of a Multiple word Term. For example, to search for economics and keynes that are within 10 words apart:
- Boosting a Term
To apply more value to a term, you can use the ^ character. For example, you can try the following search:
Which will give more value to the term "Keynes"
