When using trackerfilter with sqlsearch option it does not work as expected

• Regression
• Usability

When I use trackerfilter with the option sqlsearch in a wiki page to search a tracker it does not work as expected.

On PCs running Windows 7 and Windows 10 respectively. I can reproduce the problem in Tiki14.0 and 14.2 (both with MYSQL). In both versions there is no search box created on the wiki page with trackerfilter to enter the search string.

I have tested on the demo site and the versión 14.x demo site has the same problem.

Versión 12.x on the demo site does give a me a field to enter the search string, however, it appears to only search for the string in the first field and not in both fields.

To reproduce:
I created a Tracker with 2 fields ( "Name" a Text Field and "Description" a TextArea Field).

Then I créated a Wiki page with:
Missing or incorrect trackerId parameter for the plugin. List Trackers

In versión 14.x wiki page does not give área to enter search string.
In versión 12.x wiki page gives área to enter search string but search only appears to search first field regardless of field(s) requested. In my example there are two ítems. The word "Green" appears in ITEM1 field 2 and in ITEM2 field 1. If I search for Green only ITEM2 is listed (where Green appears in field1). If I search for "fruit" which appears in field 2 of both ítems there are no records found.
I understood that sqlsearch option should find the search string in any of the fields specified i.e. in my case "green" in field 1 AND/OR field2.

I have listed below:
tracker_1.csv to recreate the simple tracker used
itemId,status,created,lastModif,"Name — 1","Description — 2",
1,o,1453722833,1453722833,"Apple","A green or red fruit",
2,o,1453722869,1453722869,"Green","The color of some fruits",

I have uploaded the following images:
tiki14.png a screen shot showing the filter created which has no space to enter data in 14.x
tiki12.png a screen shot showing the filter created which has space to enter data in 12.x
tiki12_incorrect.png a screen shot showing how search does not opérate as I expected in 12.x only Ítem2 is listed and not Item1 despite the search string appearing in field 2 of first Ítem.
