The advance search is not working for “unbounded options” fields - wso2

Question

In WSO2 Governance registry (version 5.0.0), the advance search is not working for the scenario involving “unbounded options” fields. Here is a test case I tried. Created a new artifact type with following field. Artifacts list page renders fine. Then through advance search page, searched for the criteria “subheadingOne=value1 AND subheadingone=value2” , search comes back with no items.
Any hint what I am doing wrong?
Where can configure the interpretation of multiple values for an “options” field to be interpreted as “AND” vs “OR’ operation?
<table name="Heading" columns="3" maxoccurs="unbounded">
<subheading>
<heading>subheading One</heading>
<heading>subheading Two</heading>
<heading>subheading Three</heading>
</subheading>
<field type="options">
<name>subheadingOne</name>
<values>
<value>value1</value>
<value>value2</value>
<value>value3</value>
</values>
</field>...
</table>

Answer 1

This is a known bug in 5.0.0 and it is being fixed in Governance Registry 5.2.0 simply using a the normal search bar.
Let's say users want to search subheadingOne which value1 they can simply run the following query,
heading_subheadingOne:value1
<table_name>_<filed_name>:<search_value>
You can only search by AND operator in GReg publisher and store. For that please find the below sample,
heading_subheadingOne:value2 heading_subheadingTwo:test
In here the space denotes the AND operation.
You can find more GReg 5.2.0 search keywords from here. If you want to see some sample queries please visit this post.
you can download a nightly build of GReg 5.2.0 beta from here.
Hope this helps.
