Search engine files:

* search.php - search query page, you can edit this file to customize the search box, or you can copy search box scripts to other html file;
* searchresult.php - search result page, you can edit this file to customize the search result page;
* searchfunc.php - search function scripts, do not modify it;
* searchdb.php - search engine database file, do not modify it;

If you have selected php search engine report, there may be two other files:
* report.php - search reports page
* search.log - search log file

To add site search to your site do the following:
1. Upload search engine files to the web server, using any FTP client (e.g., CuteFTP).
2. run search.php to access the search query page. You can also copy the form in search.php file to other web page to access the search box.

To view search engine reports of your website search engine, do the following:
1. Upload search engine report files to the web server, using any FTP client (e.g., CuteFTP). These two files should be placed at the same directory as search engine files.
2. Set CHMOD for search.log file as 666 (read/write for user/group/all) 
3. run report.php to view search reports.

What is CHMOD?

CHMOD is to change file attributes. To active the report function of php search engine, you must set CHMOD for "search.log" file as 666 (read/write for user/group/all).

How to CHMOD a file?

You can use your ftp client software (e.g. CuteFTP) to CHMOD a file, it's easy to do that. 
After uploading search engine files to your ftp server, in the server file list, right click "search.log" file, on the popup menu, click "Properties/CHMOD" or "Attributes/CHMOD", in the "properties" window, set "permission" to "666". Then the attribute of file "search.log" will be "-rw-rw-rw-".
