> Currently, Calcite compose some field conditions to {{SEARCH/SARG}} operator (for example: {{field IN (scalar)}}, {{field <> ...}}, {{field = value1 OR field = value2}}, etc). This operator is not supported natively by Ignite Calcite engine and converted back to original expression using {{RexUtil.expandSearch}} method on the {{RexToLixTranslator}} phase. 
>  Such behavior forces Ignite to use full table scan instead of indexes in some cases. For example, if {{field}} is indexed, with {{field IN (1, 2)}} condition usually is much faster to scan index for 2 values, then full scan table and filter out results. For {{OR}} operator {{OrToUnion}} rule can't be applied and there will be full table scan again.
>  We should support index traversing using SEARCH/SARG operator.
>  Alternatively we can convert {{SEARCH/SARG}} to {{UNIONs}} (similarly to {{OrToUnion}} rule), but this approach will extend plan search space a lot.
