After I do a scan, when I go back to check the Analysis Filter settings (before I run the scan again) they are gone. What am I doing wrong? I assume I should not have to add them again for each scan, right?

1)
Are you sure you actually added them using the [ + ] button?
(Many people forget this.)

2)
Are you sure they are not still there if you click the "down" arrow to see the list?
(The text field box will be cleared. But the filters are still in the list.)

The + button did the trick Thanks!

Two more questions:

I only want to index pages that start with http://www.mydomain.com/page?lvl
(i.e. http://www.mydomain.com/page?lvl0, http://www.mydomain.com/page?lvl01&lvl1=2 etc)

I thought the correct regex would be http://www.mydomain.com/page?lvl[.]+ but that's not working for me.

Also, in the "Limit analysis of internal URLs..." file extension .htm appears by default. I don't want it limited to htm extensions. Can you please explain how that works? Can I just leave it as is?

Assuming you have set website root to http://mydomain.com


> pages that start with http://www.mydomain.com/page?lvl

a "limit to" regex filter would look like this
"::page\?lvl" without the ""

You could add [ + ] that to both

"output filers"

"analysis filters"

As you limit output and analysis/crawl to specific URLs you may need to add URLs to "start search from paths":

Be sure not to have any incorrect filters in the lists since that can really break the crawl. If you continue to have problems, feel free to email directly with your project file:

> "Limit analysis of internal URLs..." file extension .htm appears by default

Please click the "down" arrow. You will see lots of file extensions are in the list. (Not just the one you mention!)

If you do not want to use file extensions (although the list is extremely comprehensive) there is also a list using MIME types meaning you *can* remove all the file extensions from the list if you wish using the [ - ] button. However, unless you are very sure, I would recommend against it


> Can you please explain how that works?

Based on your questions, I think you should check his page about how the [ + ] [ - ] and drop down lists work in A1SG configuration (basicly, all items in the dropdown list are active/selected)
