1. A method for query generation from a previous result set, the method comprising: applying an initial query against a database in a database management system executing in memory by at least one processor of a host server; producing a result set of different records in response to the initial query, each record of the result set includes a plurality of different fields and content in each of the different fields; selecting a set of records in the result set; identifying commonalities in the selection of records, the identified commonalities including at least a portion of identical content in the different fields in the selection of records; establishing a strictness parameter that dictates a precision to which a derived query is generated based upon the selection of records, wherein the strictness parameter includes a less strict form only requiring a partial matching of content in only a subset of fields of records with commonality of identical content and a more strict form requiring a complete matching of content in all fields of records with commonality of identical content, wherein the precision specifies a first number of different fields with a quantity of content from the identified commonalities to be included in the derived query according to the less strict form and a second number of different fields with a quantity of content from the identified commonalities to be included in the derived query according to the more strict form, wherein the first number is lower than the second number, and wherein derived query when executed against the database would produce the selection of records; applying the strictness parameter to the selection of records; generating the derived query according to the identified commonalities and the applied strictness parameter, wherein the derived query includes either the first number or the second number of different fields and a quantity of content in each of the different fields from the identified commonalities; and storing the derived query for subsequent use in querying the database.
