| Option | Result |
| None |
By default will search for entries containing any of the words in the text search
box. Also by default, the * operation will be conducted for each word and using AND between two words will result
in the + operation.
|
| * |
An asterisk immediately following a word or word fragment will search for entries containing the first part of the
word matching exactly. For example, pharma* will find entries containing the word pharma, pharmaceutical,
pharmaceuticals, etc.
|
| + |
A plus sign in front of a word will search for entries that contain that word. For example, Anne +Spencer will
search for entries containing both words.
|
| - |
A minus sign in front of a word will search for entries that do not contain that word but that do contain the
other words in the text search. For example, Anne -Spencer will search for entries that contain the word Anne
but do not contain the word Spencer.
|
| " |
A phrase that is enclosed within double quote (" ") characters matches the exact phrase enclosed.
For example, "Anne Spencer" will search for the exact match to the phrase Anne Spencer.
|
| > < |
These two operators are used to change a word's contribution to the relevance (or importance) of finding the word.
The > increases the relevance and the < decreases it. For example, green >chemistry will give higher
relevance to entries containing the word chemistry than entries containing the word green.
|
| ( ) |
Parentheses are used to group words and to give the group higher precedence in the search. Parenthesized groups
can be nested. For example, (Anne Spencer) will give higher precedence to entries containing Anne Spencer grouped
together than where the words are separated in the entry.
|
| ~ |
A tilde before the word causes the word's contribution to the relevance (or importance) to be negative. It's
useful for marking noise words. A search result that contains such a word is rated lower than others, but is not
excluded altogether, as it would be with the - operator. For example, Anne ~Spencer gives higher precedence to
entries that contain the word Anne without the word Spencer, but will still return entries that contain the word
Spencer.
