Merge selected values of two checkboxes

[bever]

Hi All,

I would like to merge the selected values from 2 checkboxes both working on the same research field (myField).

Checkboxes test1 returns: ( myField="staticValue1" OR myField="staticValue2" OR myField="staticValue3" ) when all boxes are selected and

Checkboxes test2 returns ( myField="staticValue4" OR myField="staticValue5" OR myField="staticValue6" ) when all boxes are selected.

I finally merge the two strings in my search by doing:

<param name="search">index="index_test" ($test1$ OR $test2$) </param>

This works fine as long as at least one box is checked in each checkboxes.

Is there a way to handle this situation by avoiding an incomplete statement like ( OR $test2$) ?

I would like to avoid the use of only one checkboxes for all my choices as I have to group them by theme.

Thank you for your help

I like your answer with ValueSetter+ArrayValueSetter better, but here's a second way to do it. You make the OR itself dynamic and you use requiredKeys param on ValueSetter to only create the OR when it's needed.

<module name="ValueSetter">
  <param name="name">conditionalComma</param>
  <param name="value">OR</param>
  <param name="requiredKeys">test1,test2</param>

  <module name="Search">
    <param name="search">$test1$ $conditionalComma$ $test2$</param>

(Incidentally one might think your answer would result in a trailing OR if one side or the other was empty, but that problem is avoided because ArrayValueSetter is smart enough to ignore null entries in the array.)

A ValueSetter followed by an ArrayValueSetter does the job: the results from the two checkboxes are merged in the ValueSetter and then parsed into the search string format.
$mergedResults$ contains in the end:

 ( myField="staticValue1" OR myField="staticValue2" OR myField="staticValue3" OR myField="staticValue4" OR myField="staticValue5" OR myField="staticValue6" )

<module name="ValueSetter">
            <param name="name">testResultArray</param>
            <param name="value">$test1.rawValue$,$test2.rawValue$</param>
            <param name="delim">,</param>  

         <module name="ArrayValueSetter">
                <param name="name">mergedResults</param>
                <param name="array">$testResultArray$</param>
                <param name="template">$value$</param>
                <param name="separator">+OR+</param>
                <param name="outerTemplate">( $value$ )</param>
