Hi Iván,
The results are the same, but the number the query gives is measuring
different things.
In the first query, you get one line per publication - total 1085
results = 1085 *publications*
In the second query, you get one line per author per year - total 573
results = 573 *author/year pairs*.
Each line in the second query has a count of the publicationsfor that
person in that year, eg Verónica Cristina Trujillo González has seven
lines for different years, but a total of 14 papers (1x in 2010, 3x in
2011, 4x in 2012...).If you total up all the publications, you get
1085 across all author/years - the same as your initial query.
You can't easily see that total in the query results, but you can
check it by exporting the table, dropping it into a spreadsheet, and
summing that column.
Andrew.

Hi everyone,
From some months ago I am having a doubt about one query I made. In this
query [1] I get 1085 items and I would like to get the same but as a bar
chart. Thus I have this second query [2]. However, I don't know why in
the second query I get only 573 items... The number of items differ a
lot, but practically both are the same.
What could be happening?
Thanks in advance for your time!
Regards,
Iván
