Pull Request for Issue #28239.

Summary of Changes

Depending on the language and smart search settings, smart search might find a lot of compound words and tokens for a small search entry. These tokens then are all converted into code for the highlighting script, which is then added to the URL of each search result. In worst case, this can make the URL to long to be processed by the webserver. This PR limits the maximum amount of tokens to 10, so that doesn't get out of hand. Yes, this does mean, that some terms, which would be part of the search result, don't get highlighted, but I'd rather have some terms not highlighted than the page breaking completely.

Testing Instructions

Search for something with more than 10 different words, for example in the test sampledata "Thanks for helping us to test Joomla! We're getting ready for the release of Joomla and we appreciate you helping us". Look at the sourcecode of the page and look for the block containing "class": "js-highlight",. Below you will find a list of all search terms it is highlighting.
