<!--ChaptocEnd--><p>You can search for any word or phrase on a Web site by just ust typing the word or phrase into a query form and clicking the
|
|
button to execute the query (for example, the Execute Query button on the sample query form). Searches produce a list of files
|
|
that contain the word or phrase no matter where they appear in the text. </p>
|
|
<p>This list gives the rules for formulating queries: </p>
|
|
<ul>
|
|
<li><p align=left>Multiple consecutive words are treated as a phrase; they must appear in the same order within a matching document.</p>
|
|
</li>
|
|
<li><p align=left>Queries are case-insensitive, so you can type your query in uppercase or lowercase. </p>
|
|
</li>
|
|
<li><p align=left>You can search for any word except for those in the exception list (for English, this includes <em>a</em>, <em>an</em>, <em>and</em>, <em>as</em>, and other
|
|
common words), which are ignored during a search.</p>
|
|
</li>
|
|
<li><p align=left>Words in the exception list are treated as placeholders in phrase and proximity queries. For example, if you searched
|
|
for “Word for Windows”, the results could give you “Word for Windows” and “Word and Windows”, because <em>for </em>is a
|
|
noise word and appears in the exception list.</p>
|
|
</li>
|
|
<li><p align=left>Punctuation marks such as the period (.), colon (:), semicolon (;), and comma (,) are ignored during a search.</p>
|
|
</li>
|
|
<li><p align=left>To use specially treated characters such as &, |, ^, #, @, $, (, ), in a query, enclose your query in quotation marks (“).</p>
|
|
</li>
|
|
<li><p align=left>To search for a word or phrase containing quotation marks, enclose the entire phrase in quotation marks and then
|
|
double the quotation marks around the word or words you want to surround with quotes. For example, “World-Wide
|
|
Web or ““Web””” searches for <em>World-Wide Web or “Web”.</em></p>
|
|
</li>
|
|
<li><p align=left>You can use <a href="#Operators">Boolean operators</a> (<strong>AND</strong>, <strong>OR</strong>, and <strong>NOT</strong>) and the <a href="#Operators">proximity operator</a> (<strong>NEAR</strong>) to specify additional
|
|
search information.</p>
|
|
</li>
|
|
<li><p align=left>The <a href="#Wildcards">wildcard character</a> (*) can match words with a given prefix. The query <tt>esc*</tt> matches the terms “ESC,” “escape,”
|
|
and so on.</p>
|
|
</li>
|
|
<li><p align=left><a href="#FreeTextQueries">Free-text queries</a> can be specified without regard to query syntax.</p>

|
<p>Hints: </p>
|
|
<ul>
|
|
<li><p align=left>You can add parentheses to nest expressions within a query. The expressions in parentheses are evaluated before the
|
|
rest of the query.</p>
|
|
</li>
|
|
<li><p align=left>Use double quotes (“) to indicate that a Boolean or <strong>NEAR</strong> operator keyword should be ignored in your query. For
|
|
example, “Abbott and Costello” will match pages with the phrase, not pages that match the Boolean expression. In
|
|
addition to being an operator, the word <em>and</em> is a noise word in English.</p>
|
|
</li>
|
|
<li><p align=left>The<strong> NEAR</strong> operator is similar to the <strong>AND</strong> operator in that <strong>NEAR</strong> returns a match if both words being searched for
|
|
are in the same page. However, the <strong>NEAR</strong> operator differs from <strong>AND</strong> because the rank assigned by <strong>NEAR</strong> depends
|
|
on the proximity of words. That is, the rank of a page with the searched-for words closer together is greater than or
|
|
equal to the rank of a page where the words are farther apart. If the searched-for words are more than 50 words apart,
|
|
they are not considered near enough, and the page is assigned a rank of zero.</p>
|
|
</li>
|
|
<li><p align=left>The <strong>NOT</strong> operator can be used only after an <strong>AND</strong> operator in content queries; it can be used only to exclude pages
|
|
that match a previous content restriction. For property value queries, the <strong>NOT</strong> operator can be used apart from the
|
|
<strong>AND</strong> operator. </p>
|
|
</li>
|
|
<li>The <strong>AND</strong> operator has a higher precedence than <strong>OR</strong>. For example, the first three queries are equal, but the fourth is
|
|
not:<p align=left>a AND b OR c<br>
|
|
c OR a AND b<br>
|
|
c OR (a AND b)<br>
|
|
(c OR a) AND b</p>
|
|
</li>
|
|
</ul>
|
|
<p><strong>Note   </strong>The symbols (&, |, !, ~) and the English keywords <strong>AND</strong>, <strong>OR</strong>, <strong>NOT</strong>, and <strong>NEAR</strong> work the same way in all languages
|
|
supported by Index Server. Localized keywords are also available when the browser locale is set to one of the following six

<h1><a href="#TOP"><img src="up.gif" alt="To Top" align=middle border=0 width=14 height=11></a><a name="PropertyValueQueries">Property Value Queries</a></h1>
|
|
<p>Property value queries can be used to find files that have property values that match a given criteria. The properties over which
|
|
you can query include basic file information like file name and file size, and ActiveX properties including the document
|
|
summary (abstract) that is stored in files created by ActiveX-aware applications. </p>
|
|
<p>There are two types of property queries:</p>
|
|
<ul>
|
|
<li><p align=left><a name="PropertyValueQueries"><em>Relational property queries</em> consist of an “at” character (@), a </a><a href="#PropertyNames">property name</a>, a <a href="#RelationalOperators">relational operator</a>, and a <a href="#PropertyValues">property
|
|
value</a>. For example, to find all of the files larger than one million bytes, issue the query <tt>@size > 1000000</tt>.</p>
|
|
</li>
|
|
<li><p align=left><em>Regular expression property queries</em> consist of a number sign (#), a <a href="#PropertyNames">property name</a>, and a <a href="#RegularExpressions">regular expression</a> for the
|
|
<a href="#PropertyValues">property value</a>. For example, to find to find all of the video (.avi) files, issue the query<tt> #filename *.avi</tt>. Regular
|
|
expressions will never match the special properties contents (<tt>#contents</tt>) and all (<tt>#all</tt>). There may also be additional
|
|
format-specific properties that cannot be matched (for example, <tt>#HtmlHRef</tt> for HTML pages).</p>
