Allow multiple searches on single URLs

[rieje]

I came across this review which suggests it's possible to perform multiple searches at once. The example was:

!d php date format for a bang that searches three developer documentation sites, and it will run the search in three tabs.

That doesn't work though, performing a search for "php date format" instead, though this is probably the desired behavior anyway.

So is there a way to perform multiplie searches at once, opening each search term as a different tab (first search term in current tab)? I imagine something like !!d php date format or !d, php date format.

Hi, it is possible to assign multiple URLs to one bang by pressing the "+" button to the right of a bang.

e.g.

Click the right-most "+" and you get a new URL box to write into

Now when I search !d time it opens 2 tabs:

I mean !d php date format searches for "php", "date", and "format" on the same site in different tabs like what the review of the extensions suggests, so you don't have to !d php, !d date, and !d format separately.

I see. Yeah that's possible, as suggested it would need some sort of command modifier to indicate that you want to do that.
What about if you want to search for more than one word? I feel it could get quite complicated

Great extension, been using it for a while and I also have similar case to OP--looking forward to try @Zheckan's PR once it's merged.

What I'd love though is something a little more powerful: multiple searches on different sites at the same time. For example (I haven't given much thought of the implementation): !!d,g cats opens 2 tabs searching for "cats" on duckduckgo.com and google.com, assuming d and g, respectively. This is useful because I have some use cases where I want to quickly e.g. search a product across my particular defined set of shopping websites, or search for subtitle files for a video across a several services at once and compare the translations. Currently, I'd have to e.g. open a tab, enter "!a keyboard", open another tab, enter "!b keyboard", ... etc.
