Stop words
Stop words are commonly used words that Arctera Personal Archive ignores when processing a search. Because these words are excluded from search matching, including them in a query does not help narrow the search results.
Understanding stop-word processing helps you determine why some words in a query do not affect the returned results.
Arctera Personal Archive treats the following English words as stop words:
-
a, an, and, are, as, at
-
be, but, by
-
for
-
if, in, into, is, it
-
no, not
-
of, on, or
-
such
-
that, the, their, then, there, these, they, this, to
-
was, will, with
Stop-word support is available for English searches. Support for Japanese stop words is available only if your organization subscribes to enhanced Japanese search.
Stop words in Boolean searches
The words
AND, OR, and NOT function as operators when they are used in a Boolean operator search. In this context, Arctera Personal Archive processes them as Boolean operators instead of ignoring them as stop words.
For example:
cloud AND computing
In this search,
AND instructs the application to return items that contain both cloud and computing.
Stop words in proximity searches
Proximity search results can contain stop words. However, Arctera Personal Archive excludes stop words when calculating the number of words between the specified search terms.
For example:
"cloud computing"~5
The application calculates the proximity between cloud and computing without including any stop words that occur between them in the proximity word count.
Stop words in hit highlighting
Hit highlighting supports stop words for tenants where stop-word indexing is enabled.
In Native Viewer, stop words are included in the highlighted terms and their occurrence counts.
Understanding how stop words are processed helps you create effective search queries and interpret search and hit-highlighting results correctly.
Special characters
Arctera Personal Archive omits the following special characters from searches:
* @ % ^ - + = _ { } [ ] , < > ; : / / ?
Special cases
-
The words AND, OR, and NOT act as operators in a Boolean operator search. See Boolean operators.
-
Question marks and asterisks act as wildcard characters in a wildcard search. See Wildcard characters.
