<div class="textblock"><p><code><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a></code> is a <code><a class="el" href="classicu_1_1SearchIterator.html" title="SearchIterator is an abstract base class that provides methods to search for a pattern within a text ...">SearchIterator</a></code> that provides language-sensitive text searching based on the comparison rules defined in a <a class="el" href="classicu_1_1RuleBasedCollator.html">RuleBasedCollator</a> object. </p>
<p><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a> ensures that language eccentricity can be handled, e.g. for the German collator, characters ß and SS will be matched if case is chosen to be ignored. See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">"ICU Collation Design Document"</a> for more information. </p>
<p>There are 2 match options for selection:<br />
Let S' be the sub-string of a text string S between the offsets start and end [start, end]. <br />
A pattern string P matches a text string S at the offsets [start, end] if </p><pre>
option 1. Some canonical equivalent of P matches some canonical equivalent
of S'
option 2. P matches S' and if P starts or ends with a combining mark,
there exists no non-ignorable combining mark before or after S?
in S respectively.
</pre><p> Option 2. will be the default. </p>
<p>This search has APIs similar to that of other text iteration mechanisms such as the break iterators in <code><a class="el" href="classicu_1_1BreakIterator.html" title="The BreakIterator class implements methods for finding the location of boundaries in text...">BreakIterator</a></code>. Using these APIs, it is easy to scan through text looking for all occurrences of a given pattern. This search iterator allows changing of direction by calling a <code>reset</code> followed by a <code>next</code> or <code>previous</code>. Though a direction change can occur without calling <code>reset</code> first, this operation comes with some speed penalty. Match results in the forward direction will match the result matches in the backwards direction in the reverse order </p>
<p><code><a class="el" href="classicu_1_1SearchIterator.html" title="SearchIterator is an abstract base class that provides methods to search for a pattern within a text ...">SearchIterator</a></code> provides APIs to specify the starting position within the text string to be searched, e.g. <code>setOffset</code>, <code>preceding</code> and <code>following</code>. Since the starting position will be set as it is specified, please take note that there are some danger points which the search may render incorrect results: </p><ul>
<li>
The midst of a substring that requires normalization. </li>
<li>
If the following match is to be found, the position should not be the second character which requires to be swapped with the preceding character. Vice versa, if the preceding match is to be found, position to search from should not be the first character which requires to be swapped with the next character. E.g certain Thai and Lao characters require swapping. </li>
<li>
If a following pattern match is to be found, any position within a contracting sequence except the first will fail. Vice versa if a preceding pattern match is to be found, a invalid starting point would be any character within a contracting sequence except the last. </li>
</ul>
<p>A <code><a class="el" href="classicu_1_1BreakIterator.html" title="The BreakIterator class implements methods for finding the location of boundaries in text...">BreakIterator</a></code> can be used if only matches at logical breaks are desired. Using a <code><a class="el" href="classicu_1_1BreakIterator.html" title="The BreakIterator class implements methods for finding the location of boundaries in text...">BreakIterator</a></code> will only give you results that exactly matches the boundaries given by the breakiterator. For instance the pattern "e" will not be found in the string "\u00e9" if a character break iterator is used. </p>
<p>Options are provided to handle overlapping matches. E.g. In English, overlapping matches produces the result 0 and 2 for the pattern "abab" in the text "ababab", where else mutually exclusive matches only produce the result of 0. </p>
<p>Though collator attributes will be taken into consideration while performing matches, there are no APIs here for setting and getting the attributes. These attributes can be set by getting the collator from <code>getCollator</code> and using the APIs in <code><a class="el" href="coll_8h.html" title="C++ API: Collation Service. ">coll.h</a></code>. Lastly to update <code><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a></code> to the new collator attributes, <code>reset</code> has to be called. </p>
<p>Restriction: <br />
Currently there are no composite characters that consists of a character with combining class > 0 before a character with combining class == 0. However, if such a character exists in the future, <code><a class="el" href="classicu_1_1StringSearch.html" title="StringSearch is a SearchIterator that provides language-sensitive text searching based on the compari...">StringSearch</a></code> does not guarantee the results for option 1. </p>
