Build searchable documentation database



builddocsearchdb(folder) builds a searchable database, also referred to as a search index, from HTML files in the specified folder.

The builddocsearchdb function creates a subfolder, helpsearch-v4, to contain the database files. The database enables MATLAB® to search for content within the HTML files assuming the MATLAB version is the same version used to create the database.

Build a search database for custom help files.

The Upslope Area Toolbox is a sample toolbox used for demonstrating how to create a custom toolbox and supporting documentation. The upslope toolbox folder included with this example contains a file named info.xml, which is required to display custom documentation, and a subfolder named html, which contains HTML documentation and supporting files.

Create a search database for the Upslope Area Toolbox.

folder = fullfile("upslope","html");
Process Duration: 0.002378
Successfully created search database.

Open the Help browser and search for the term tarboton, which appears in several of the example help files. The search returns the results in the MathWorks® documentation.

On the left side of the page, under Refine by Source, select Supplemental Software to view the results for the Upslope Area Toolbox.
