The administrator can define a list of words which, if not in an exact phrase, will be ignored. These are typically conjunctions and direct and indirect articles. Additionally, the default conjunction (OR or AND) between words can be defined. See the Admin > Configure > Resource lists interface.
There are two types of search available:
A set number of database fields are searched:
Partial word searches are the default unless the search term is an exact phrase
You can use control words as noted below
The restrictions noted below on searches using the abstract, note, metadata, and long custom fields pertain here
1 OR 2 AND 3 NOT 4 OR 5
will be grouped as 1 OR (2 AND 3 NOT 4) OR 5
In both types of search, the following rules hold for the word search phrase:
You can use the control words AND, OR and NOT and can group words into exact phrases using double quote marks
AND, OR and NOT are case-sensitive and function as control words only outside exact phrases
The wildcard characters ? (zero or one character) and * (zero or multiple characters) can be used. In an exact phrase, these characters will be removed
The use of wildcard characters disables partial word matching
The wildcard ? will not match a single UTF-8 character due to the multibyte nature of UTF-8. Use * instead
Searches are case-insensitive
A space not in an exact phrase will be treated as OR or AND depending on the configuration of the WIKINDX
All non-alphanumeric characters (such as punctuation) will be ignored unless the character is a wildcard that is not in an exact phrase
OR words following AND or NOT will be grouped. You might choose, therefore, to have a string of OR words at the start of the phrase. Some examples:
word1 AND word2 OR word3 OR word4 NOT word5 word6
// gives
word1 AND (word2 OR word3 OR word4) NOT (word5 OR word6)
word1 word2 OR word3 word4 NOT word5 word6 AND word7
// gives
word1 OR word2 OR word3 OR word4 NOT (word5 OR word6) AND word7
NOT word1 word2 OR word3 OR word4 NOT word5 word6
// gives
NOT (word1 word2 OR word3 OR word4) NOT (word5 OR word6)
which is equivalent to
NOT (word1 OR word2 OR word3 OR word4 OR word5 OR word6)
You can attach files of any type to resources. For those that are text-type documents, a small number can be converted to text and cached for fulltext search from within Advanced Search. Following is a list of the major text-type document formats and their caching support for fulltext search.
The documents are analyzed according to their mime-type and then according to their extension if there is any ambiguity.
The plain/text
mime-type is a generic format that covers a multitude of files.
As the search targets written documents, attachments with the following extension are excluded: CSV, TSV, SYLK.
Then encoding is assumed to be UTF-8 only, unless the format specification says otherwise.
Better PDF extraction quality requires the xpdftotext plugin.
Extracting PS (PostScript) files requires the ps2pdf converter included in Ghostscript.
Extracting DVI (DeVice Independent) files requires the catdvi converter included in TeX Live and others TeX distributions.
Extracting DJV (DjVu) files requires the djvutxt converter included in DjVuLibre.
