getPartialMatchTransformer()
If defined, this will be applied over the value of the
FileToEntityLookup.getRelatedFieldName() just before it is searched on the DB.For example if SKU's = "0102-37", "0102-38" etc; and we want the same file mapped to all SKU that match ="0102-". Hence in this example, by having a transformer that applies partialMatchTransformer("0102-37") ~> "0102-%" and then the partial match will match SKU values that start with 0102- If not partialMatchTransformer is supplied then the match is conducted with %fieldValue%. If partialMatchTransformer is used then it is the role of the transformer to also provide the DB like match characters '%' |

include it in the Lookup for Products. |

Query. The Query passed here will already have the FileToEntityLookup.relatedFieldName set.
In addition to that if one wants to do things like range searches or regular expression matches etc, one may customize that here.entityQuery - as Querypublic Pattern getSupportPartialMatchOn()
Pattern set; it will see if the value being looked for contains supportPartialMatchOn as a subsequence using Matcher.find(); and then if FileToEntityLookup.getRelatedFieldName() matches the file name partially also, if so it will
include it in the Lookup for Products. If false it will only look for exact matches.
Query.getEntity() is NOT Queryable.exactMatch(); then one can skip this as it is expected that
the underlying DAO will support partial search on Queryable fields that are marked as false for exact match.public void setSupportPartialMatchOn(Pattern supportPartialMatchOn)
