<ul>

||
|
|
<li><p align=left><em>Different languages were used to filter the page and issue the query.</em> The split of a page into words (the
|
||
|
|
fundamental unit stored in the index) is a language-dependent process. When a query is issued from one language and
|
||
|
|
the document was filtered in another, query results can be unpredictable. The locale used to filter a document is
|
||
|
|
dependent on the filter. Some file formats, such as Microsoft Word, mark documents with a language; this mark is used
|
||
|
|
during filtering. Other formats, such as plain text, contain no language specifier. Most filters default to the system locale
|
||
|
|
for these files. The locale for the query is specified by use of the <strong>CiLocale</strong> variable. If <strong>CiLocale</strong> is not specified, the
|
||
|
|
locale of the browser is used (if available) or the default locale of the server. </p>
|
||
|
|
</li>
|
||
|
|
<li><p align=left><em>The page has not yet been filtered.</em> There is often a delay between the time a page is modified and the time it is
|
||
|
|
indexed. You can use the Performance Monitor or an administrative query to determine the number of pending pages.
|
||
|
|
The <strong>CiOutOfDate</strong> variable is set to TRUE if one or more files remain to be filtered. </p>
|
||
|
|
</li>
|
||
|
|
<li><p align=left><em>An error occurred during filtering of this document.</em> There are a number of reasons why a document may not have
|
||
|
|
been filtered. See the <a href="filtrhlp.htm">filtering</a> page for a detailed discussion of filtering. You can check for errors either in the event log
|
||
|
|
or by issuing the a query over the “unfiltered property,” using the <a href="adminhlp.htm#UnfilteredFiles">administrative query</a> for unfiltered files. </p>
|
||
|
|
</li>
|
||
|
|
<li><p align=left><em>The query was too complex. </em>Certain classes of resource intensive queries are turned off when <strong>CiForceUseCi</strong> is set to
|

|
|
TRUE. When results are missing for this reason, the <strong>CiQueryIncomplete</strong> variable is set to TRUE. </p>
|
||
|
|
</li>
|
||
|
|
<li><p align=left><em>The query took too much CPU time.</em> An administrator can limit the amount of CPU time a single query can consume.
|
||
|
|
When this limit is reached, the <strong>CiQueryTimedOut</strong> variable is set to TRUE. </p>
|
||
|
|
</li>
|

|

<li><em>You do not have permission to read the page.</em> A query result will not be returned for a page that you do not have

permission to read. See <a href="sechelp.htm">Security</a> for a detailed discussion of security as it relates to Index Server.</li>
