Creating the Full-Text Search Database

When a user initiates a full-text search, the JavaHelp system full-text search engine searches a special search database to find matches quickly. You use the jhindexer command to create the search database for your help topics.

The search database created by the jhindexer command consists of six files located in a folder named JavaHelpSearch. As described in Setting Up a JavaHelp System, the search database folder is usually located in the same folder as the rest of the help metadata files.

Example

The following example describes how to use the jhindexer command in its simplest form. For details about other features of the jhindexer command, see The jhindexer Command.

The example assumes that your help information is arranged in the following hierarchy:

To create a full-text search database:

Make the ...\help folder the current folder
Specify the top-level folders as arguments to the jhindexer command, as follows:
```
jhindexer topic1 topic2 topic3
```
The jhindexer command is located in the javahelp\bin folder of the JavaHelp system release.

The jhindexer command recursively descends the help hierarchy, indexing all the files it encounters. When finished, jhindexer places the search database files in a folder named JavaHelpSearch in the current folder:

To verify the validity of a full-text search database:

Make the ...\help folder the current folder
Specify the JavaHelpSearch folder as the argument to the jhsearch command:
```
    jhsearch JavaHelpSearch
```
