3.1 Simple search

3.1.1 Keyword search

You can perform full-text searches among all the free text annotation by entering a keyword with the "Keyword" option (default). Please note searches cannot yet be performed using double byte characters, such as Japanese Kanji or double byte Roman characters.

AND query-	The query specifies two or more terms for retrieving all documents which contain both terms. You can insert the AND operator between the terms. e.g., protein AND cytoplasm
OR query-	The query specifies two or more terms for retrieving all documents which contain either term. You can insert the OR operator between the terms e.g., protein OR cytoplasm
NOT query-	The query specifies two or more terms for retrieving all documents which contain a first term but don't contain the terms which follow. You can insert the NOT operator between the terms to do a NOT query e.g., protein NOT cytoplasm
Substring matching-	Only prefix matching is allowed.      e.g., receptor* (returns documents which contain terms that begin with the string 'receptor')
