| 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, green +chemistry 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, green -chemistry will search for entries that contain the word green but do not contain the word chemistry. |
| > < | 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, (green chemistry) will give higher precedence to entries containing green chemistry 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, green ~chemistry gives higher precedence to entries that contain the word green without the word chemistry, but will still return entries that contain the word chemistry. |
| " | A phrase that is enclosed within double quote (" ") characters matches the exact phrase enclosed. For example, "green chemistry" will search for the exact match to the phrase green chemistry. |
