<h2>What is This?</h2> |
| 7 |
<p>This is a full-text search system. You can search for documents including some specified words.</p> |
| 8 |
<h2>How to Use</h2> |
| 9 |
<p>Input search phrase into the field at the top of the page. For example, if you search for documents including "computer", input the following.</p> |
| 10 |
<pre>computer |
| 11 |
</pre> |
| 12 |
<p>If you search for documents including both of "network" and "socket", input the following.</p> |
| 13 |
<pre>network socket |
| 14 |
</pre> |
| 15 |
<p>It is the same as the following.</p> |
| 16 |
<pre>network & socket |
| 17 |
</pre> |
| 18 |
<p>If you search for documents including "network" followed by "socket", input the following.</p> |
| 19 |
<pre>"network socket" |
| 20 |
</pre> |
| 21 |
<p>If you search for documents including one or both of "network" and "socket", input the following.</p> |
| 22 |
<pre>network | socket |
| 23 |
</pre> |
| 24 |
<p>If you search for documents including "network" but without "socket", input the following.</p> |
| 25 |
<pre>network ! socket |
| 26 |
</pre> |
| 27 |
<p>Note that the priority of "<kbd>|</kbd>" is higher than that of space, "<kbd>&</kbd>", and "<kbd>!</kbd>". So, the following is to search for documents including one of "F1", "F-1", "Formula-One", and including one of "champion" and "victory".</p> |
| 28 |
<pre>F1 | F-1 | "Formula One" & champion | victory |
| 29 |
</pre> |
| 30 |
