I have two questions:
1)
We have an application where we use the date interval in the query like this
Code: Select all
pd=2010,2020
Code: Select all
pd="2010 2020"
2)
We have also detected different search results between the web search and the OPS service. Here are both URLs we get:
Web
OPS service
As you can see, the search terms are:
Title or abstract: (elevator OR lift) AND (Lithium OR "Li-Ion")
Publication date: 2010:2020
IPC: B66B
Through the web, we get 9 results and through the service we get only 2 results and furthermore totally different. Are we doing anything wrong?
Thanks in advance.
Regards
