A Metamorph query will by default be parsed for noise before the main words are sent out to the executed search. The intent is that a user can phrase his search request in a manner which reflects how he is thinking about it, without requiring him to categorize his thoughts into a syntactical procedure.
You do have the option to keep the noise words as significant words in
the query. This choice can be invoked by setting the APICP flag
on. If off, as is the Metamorph
default used by Texis, the question parser is invoked and allowed to
exercise discretion in determining what is most important about your
query. This selection process determines what should be treated as a
search word, and therefore included in the set count and intersection
quantity assigned to each significant search item.
A need to edit these lists would be most likely to come up if one were
searching language from a different era or with a vastly different
language style; perhaps for example the Bible. Where
thee's" and "
thou's" replace "
yours", certain things should be filtered out from the query
that might not be entered in the list. These categories can be
defined as follows, where all of these categories are grouped for
APICP programming purposes under "noise".
Syntax for setting a custom list inside a Vortex script is as follows, where what you write in would override the default internal noise list:
<$noiselist = "am" "are" "was" "were" "thee" "thou" "has" "hast"
<apicp noise $noiselist>
