+<h1>C/C++ search</h1>
+
+<p>You can conduct a fully or partially qualified name search. Further
+qualifying a search increases the accuracy and relevance of search results. The
+sections below provide guidance on how to control the scope of your search
+through the use of search delimiters, correct syntax, and wildcards.</p>
+
+<p>You can search for:<br>
+<ul>
+ <li>language constructs within:
+ <ul>
+ <li>projects in your workspace</li>
+ <li>selected resources from various views</li>
+ <li>working sets</li>
+ </ul></li>
+ <li>a working set for references to particular elements</li>
+ <li>declarations of particular elements</li>
+ <li>definitions of particular elements</li>
+ <li>references of particular elements</li>
+</ul>
+</p>
+
+For information on working sets, see <b>Workbench User Guide > Concepts > Workbench > Working sets</b><br>
+
+
+ <h2>What you can search for</h2>
+ <p>The table below lists the element types that you can search for and special
+ considerations to note when searching for a given element type. You can search
+ for some or all of the element types matching a search string that you
+ specify. If you choose to search for matching elements, all types, macros, and typdefs are included in the search.</p>
+<table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="60%">
+ <tr>
+ <td width="19%"><b>Element</b></td>
+ <td width="81%"><b>Note</b></td>
+ </tr>
+ <tr>
+ <td width="19%"> Class/Struct</td>
+ <td width="81%">Searches for classes and structs.<p>You can further qualify
+ the search by specifying "class" or "struct" in front of the name
+ that you are
+ searching for. Specifying "class" or "struct" also allows you to
+ search for anonymous classes and structures.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Function</td>
+ <td width="81%">Searches for global functions or functions in a namespace
+ (functions that are not members of a class, struct, or union).<p>You can
+ specify parameters to further qualify your search. When specifying a
+ parameter list, everything between the parentheses should be valid C/C++
+ syntax.</p>
+ <p>Do not specify the return type of the function.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Variable</td>
+ <td width="81%">Searches for variables that are not members of a class,
+ struct, or union.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Union</td>
+ <td width="81%">Searches for unions.<p>Anonymous unions can be searched for by
+ specifying "union" as the search pattern.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Method</td>
+ <td width="81%">Searches for methods that are members of a class, struct, or
+ union.<p>Searching for methods also finds constructors and destructors. See
+ above note for functions.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Field </td>
+ <td width="81%">Searches for fields that are members of a class, struct, or
+ union.
+ </tr>
+ <tr>
+ <td width="19%"> Enumeration</td>
+ <td width="81%">Searches for enumerations.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Enumerator</td>
+ <td width="81%">Searches for enumerators.</td>
+ </tr>
+ <tr>
+ <td width="19%"> Namespace</td>
+ <td width="81%">Searches for namespaces.</td>
+ </tr>
+</table>
+
+<h2>How you can limit your search</h2>
+
+<p>You can limit your search to one or all of the following:</p>
+
+<ul>
+ <li>Declarations</li>
+ <li>References</li>
+ <li>Definitions (for functions, methods, variables and fields)</li>
+</ul>
+
+<p>You can control the scope of the search by specifying which of the following
+is to be searched:</p>
+<ul>
+ <li>Workspace</li>
+ <li>Working Set</li>
+ <li>Selected Resources</li>
+</ul>
+
+<h2>Wildcard characters</h2>
+<p>You can use wildcard characters to further refine your search.</p>
+<table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" bordercolor="#111111" width="60%">
+ <tr>
+ <td width="49%"><b>Use this wildcard character</b></td>
+ <td width="51%"><b>To search for this</b></td>
+ </tr>
+ <tr>
+ <td width="49%"> <samp>*</samp></td>
+ <td width="51%">Any string<p><b>Tip:<br>
+ </b> Use the character <samp>*</samp> to search for
+ operators that begin with *. See syntax examples in the table below.</td>
+ </tr>
+ <tr>
+ <td width="49%"> <samp>?</samp></td>
+ <td width="51%">A single character</td>
+ </tr>
+ <tr>
+ <td width="49%"> <samp>::</samp></td>
+ <td width="51%">Nested elements</td>
+ </tr>
+</table>
+<p><b>Tip: </b>Do not use wild cards between the brackets of a function or
+method pattern. For example, the search
+string <samp>f( * )</samp> is an invalid search that results in a search for any function <samp>f</samp>
+ because
+the asterisk is interpreted as a pointer rather than a wild card.</p>
+<h2>Syntax examples</h2>
+<p>The table below provides syntax examples and an explanation for each example
+to help you conduct an effective search.</p>

+<h2>Search results</h2>
+<p>Search results are displayed in the Search view. You can sort your search by Name, Parent Name and Path. You can also repeat
+your last search.</p>
+
+<h2>Search Concepts</h2>
+
+<h3>Declarations</h3>
+<p>According to the ANSI C++ Spec, a declaration is a statement that “introduces a name into a translation unit or re-declares a name that has been previously introduced by a previous declaration.</p>
+<p>All C/C++ search elements can be searched for declarations.</p>
+
+<h3>Definitions</h3>
+<p>Most declarations are also definitions; in other words, they also define the entity for they declare the name for. However there are some elements that can have separate definitions from their declarations.</p>
+<p>For C/C++ search the following elements can be searched for definitions:
+<ul>
+ <li>Functions/Methods – the definition is where the code implementation resides</li>
+ <li>Variable:
+ <ol>
+ <li>Extern – the definition is where the variable is initialized</li>
+ <li>Non extern - the definition of a variable is where it is declared </li>
+ </ol></li>
+ <li>Field:
+ <ol>
+ <li>Static fields - the definition of a static field is where it gets initialized</li>
+ <li>Non static fields - the definition corresponds to the fields declaration</li>
+ </ol></li>
+ <li>Namespace – the definition of a namespace is the same as its declaration</li>
+</ul></p>
+
+<h3>References</h3>
+<p>By selecting references, C/C++ search will return all of the places the selected element is used.</p>
+
+<h3>All Occurrences</h3>
+<p>Selecting ‘All Occurrences’ in the Limit To section will result in a search for declarations, definitions (if applicable) and references for whatever element or elements have been selected.</p>
+
+<h3>Any Element</h3>
+<p>Selecting ‘Any Element’ in the Search For section will result in a search for all of the listed elements plus macros and typedefs.</p>
