   We have a BE with the following RestAddress.
   
   @RestAddress (type="collection", address="/PurchaseOrder", tables="ePurchaseOrder,ePoLine", id="OrderNum",
                 fields="ePurchaseOrder.*,ePoLine.*", canRead="true", canUpdate="true", canDelete="false", canCreate="true",
                 links="PoLine:/PurchaseOrder/~{OrderNum}/PoLine"
   
   This works great for most of what we need. However, we need to pass a query of Stat LE 1 OR Stat GE 5 but this does not appear to be supported by REST. 
   
   When we use http://192.168.168.68:8940/OspreyHostBackend/web/Entities/PurchaseOrder?Stat<=2&Stat>=5
   
   We get the following logged in PASOE
   
   Client-Query: for each ePurchaseOrder WHERE ePurchaseOrder.Stat <= "2" AND ePurchaseOrder.Stat >= "5"
   
   What would be the best way to handle this? We have tried creating a REST METHOD where we can define our own query and return back the PDS. However, the response is different than that of the RestAddress.

   Hi Roger,
   
   OR is indeed difficult - as we have not real way in the URL to provide different operators than AND (&).
   
   Best I can think of right now would be a query string like this
   
   ?stat<=2&operator=or&stat>=5 
   
   But that would require an enhancement request and I'm not sure we can work on this in September still.

   Hi Mike,
   
   I hope you are well...PUG was good!!
   
   Is there a way to pass a string like filter="Stat<=2 OR Stat >=5" and then grab that on the backend and manipulate the query?

   You can "abuse" the quick search.
   
   q="Stat<=2 or Stat>=5".
   
   The Business Entity needs to implement the ISupportsQuickSearch interface and you need to code the "QuickSearch" named query.

   Hello Mike,
   
   I am going to look at this today. Can you give me a hint on where to code the quick search?
   
   I have added the ISupportsQuickSearch.
   
   Do I just check for the named query in FetchData of the BE?

   Yes - FetchData is usually the place to deal with Named Queries. I would however implement it in the Data Access class and not the Business Entity as it's query manipulation and not business logic.

    Hello Mike.
    
    I have added the -q="Stat<=2 or Stat>=5" 
    
    http://192.168.168.68:8940/OspreyHostBackend/web/Entities/PurchaseOrder?q="Stat<=2 or Stat>=5"
    
    In the DA class I do see a named query "QuickSearch". However, if log the value of the parameter to PASOE the value only has "Stat< 
    
    oCharacter = CAST (oQuickSearch:Parameters:GetItem(1):VALUE,CharacterHolder).
    
    MESSAGE "oCharacter:Value=" oCharacter:Value
    VIEW-AS ALERT-BOX.

    The following will work
    
    http://192.168.168.68:8940/OspreyHostBackend/web/Entities/PurchaseOrder?q="Stat LE 2 or Stat GE 5"
    
    
    It looks like Consultingwerk.OERA.RestResource.RestEntitiesWebHandler:FetchDataRequestFromRestRequest does not like the = in the quick search?
    
    I think I am good...thanks for the guidance!!

    I would expect that you need to URL encode space and equal signs etc.
    
    https://meyerweb.com/eric/tools/dencoder/
    
    Otherwise the = sign is treated like a separator of arguments.
