IIS URL Rewrite with multiple query string - iis-7

Question

Im really new in URL Rewriting and trying to rewrite / redirect multiple query but seems not working. Since this is the search result and comes with different filtering the queries may vary. For example is some search we may have the query of t1=something and in the other we may have t2=somethingelse and sometimes we may combine them like: t1=something&t2=somethingelse
Im using IIS7 with web.config and here is what I have done so far:
This is my example link
www.website.com/search/?t1=first&t2=second
I have tried the following and non of them actually worked:
(1)
<rewrite>
<rules>
<rule name="first" stopProcessing="true">
<match url="search/" />
<conditions trackAllCaptures="true">
<add input="{QUERY_STRING}" pattern="t1=([0-9a-zA-Z]+)" />
</conditions>
<action type="Redirect" url="search/{C:1}/" appendQueryString="false" />
</rule>
<rule name="second" stopProcessing="true">
<match url="search/" />
<conditions trackAllCaptures="true">
<add input="{QUERY_STRING}" pattern="t2=([0-9a-zA-Z]+)" />
</conditions>
<action type="Redirect" url="search/{C:1}/" appendQueryString="false" />
</rule>
</rules>
</rewrite>
(2)
<rule name="a" stopProcessing="true">
<match url="search2/" />
<conditions trackAllCaptures="true">
<add input="{QUERY_STRING}" pattern="t1=([0-9a-zA-Z]+)" />
<add input="{QUERY_STRING}" pattern="t2=([0-9a-zA-Z]+)" />
</conditions>
<action type="Redirect" url="search2/{C:1}/{C:2}" appendQueryString="false" />
</rule>
I would really appreciate any help.
Thanks.

Answer 1

Also, this post might provide the answer -
Tracking Capture Groups Across Conditions setting
EDIT: the example from the link above
Note the trackAllCaptures=true
<rule name="Back-references with trackAllCaptures set to true">
<match url="^article\.aspx" >
<conditions trackAllCaptures="true">
<add input="{QUERY_STRING}" pattern="p1=([0-9]+)" />
<add input="{QUERY_STRING}" pattern="p2=([a-z]+)" />
</conditions>
<action type="Rewrite" url="article.aspx/{C:1}/{C:2}" /> <!-- rewrite action uses back-references to both conditions -->
</rule>

I thought I'd share a link of what I had found -

Also, to separate multiple parameters you can use a pipe operator. For example, something like this:
parm1=(\w+)|parm2=(\w+)
apply target URL with {C:1} and {C:2}
So, URL like this:
yourapp/list.aspx?parm1=abc&parm2=123
will result in back references as follows - {C:1}=abc and {C:2}=123
