Mule CE 3.6.1 HTTP Request url encoding issue - http

Question

I have a Mule flow which uses HTTP Request endpoint in Mule CE3.6.1. It needs to use encoded HTTP url to get the correct data.
Please note the encoded url: /items?q=%2Blabel%3ABOTV2309H*%20%2Bparent.uri%3A%5C%2Fbristol%5C%2Ftest%5C%2Fgateway%5C%2F*&rows=100&start=0
Here is the test flow.
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
xmlns:spring="http://www.springframework.org/schema/beans" version="CE-3.6.1"

<object-to-string-transformer doc:name="Object to String"/>
<logger level="INFO" doc:name="Logger"/>
<http:request config-ref="HTTP_Request_Config_Search" path="/items?q=%2Blabel%3ABOTV2309H*%20%2Bparent.uri%3A%5C%2Fbristol%5C%2Ftest%5C%2Fgateway%5C%2F*&rows=100&start=0" method="GET" doc:name="HTTP"/>
<logger message="#[payload]" level="INFO" doc:name="Logger"/>
</flow>
</mule>
When the Mule flow runs, here is the url being requested (Found through wireshark):
/items?q=%20label%3ABOTV2309H%2A%20%20parent.uri%3A%5C%2Fbristol%5C%2Ftest%5C%2Fgateway%5C%2F%2A&rows=100&start=0
Please note %2B is replaced with %20 in two places, which obviously do not return the data I need.
Is this an issue with HTTP endpoint?
Thanks!

Answer 1

I divided the params into query and uri params. Then this issue got resolved.
<http:request config-ref="HTTP_Request_Config_Search" path="/items" method="GET" doc:name="HTTP">
<http:request-builder>
<http:query-param paramName="q" value="+label:BOTV2309H* +parent.uri:\/test\/gateway\/*"/>
<http:uri-param paramName="rows" value="100"/>
<http:uri-param paramName="start" value="0"/>
</http:request-builder>
</http:request>
