How to apply filter(s) on Mongo DB collection:

If user needs to give the filter on Mongo connection, then in the component options
the Name will be given as aggregation.pipeline and the value will be given as shown below 


Filter on string column: 

{'$match': {'column name':'data which need to be filtered in specific column '}}

EX: {'$match': {'skill': 'java'}}
Here skill is a column name and
java is a value
so, user can fetch the data based on the given value 

 

Filter on different datatype columns:

{'$match': {'columnname1': 'stringtypedata','columnname2': integerdata,'columnname3': {$gt: {$date:datetype data'}}}}


EX: {'$match': {'cancellation_policy': 'moderate','accommodates':2,'calendar_last_scraped': {$gt: {$date:'2019-03-07T00:00:00.000Z'}}}}  

Here cancellation_policy is a column name and moderate is a value and
accommodates is a column name and 2 is a value and also 
calendar_last_scraped is a column name and 2019-03-07T00:00:00.000Z is a value
