How to write dynamic query in bonita studio bdm?

I have five filter fields in my application home page (dashboard -> where I am showing all the records from h2 DB) now I want to filter the records on these fields basis.
It may require 31 (2^5 -1) queries, some are already provided as default queries.

Isn't there a way to write a dynamic query in "custom queries" or somewhere to get the desired result at UI?

Cómo definir tamaño variable a un campo tipo TEXT de un BDM en Postgresql?

Hola,
Estoy usando Bonita v.7.5 con una base de datos Postgresql v.10 en la cual tengo campos definidos tipo TEXT. Revisando el archivo XML de la BDM en los campos TEXT se crea un tamaño por defecto de 255 bytes. Por el momento cambio el valor a 1024 o un tamaño mayor. Pero quisiera saber si hay alguna forma de definirlo para que sea variable, hay un atributo a agregar?

Gracias de antemano y saludos.
