Allow documentation to return all search results

Currently, OpCon documentation only seems to return 8 search results. Usually, if I'm searching the doc, it's for an obscure detail that isn't likely to be within the top 8 results. If you're not sure what the name of the page containing the information you're looking for, this can make it very difficult to find.

An example of this would be trying to find what the syntax is for referencing a threshold's current value in an event. This information is found in Concepts -> OpCon Objects -> Properties -> Properties. However, none of these searches returned this page:
"Threshold"
"Reference Threshold"
"Threshold Value"
"Get Threshold"
"Threshold Event"
"current value of threshold" (And this one is a direct quote from the page I needed)

If the search results showed all results (or at least more than 8), there's a much better likelihood that the needed information could be found.
