Find - Error when clicking search result but result loads correctly
Hi Tomas,
The result Url has the following parameters added, I've removed the values:
?_t_id=
&_t_q=
&_t_tags=
&_t_ip=
&_t_hit.id=
&_t_hit.pos=
Thinking about it, it would kind of make sense that it does another search if statistics are enabled as I guess it's logging the fact the result has been clicked and the various parameters needed to get the result?
Assuming this is valid how would I prevent the underlying error we see?
Thanks,
Mark

I think those parameters can be used to highlight the search term on every page in the search result, even after the visitor follows the links to the pages in the search result.
Not sure how to get rid of them, though.

After a bit of digging and some help from EPiServer it seems a second search was being called on the search result page to include some related content.
This second search did not have a search term. The search code had several .Filter calls before the .For call being issued for this second search. Moving the code with the .For to before any .Filters resolved the issue (which is basically what the stack trace stated!).

Hi,
We have a search page which uses Find and I am seeing an error when the user clicks a search result but the actual page the result is for loads as expected.
The search is UnifiedSearch and we loop through the UnifiedResults in the view and use document.Url to show the link to the result. When you hover over the result there are additional paramters appended to the result which I believe are there as we have statistics enabled.
When you click on a result it seems to trigger another search, I assume as a result of the paramters? It's this second search that triggers an error behind the scenes however the page for the search result loads as expected and does not have the additional parameters appended to the Url.
The error that is raised is:
"The extension method 'For' must be called before the query has been otherwise set"
and the stack trace for this is:
System.InvalidOperationException: The extension method 'For' must be called before the query has been otherwise set

Has anyone encountered this before and know how to prevent an additional search or the error happening?
Thanks,
