Perhaps you should try some spelling variations:
delos editorial » eros editorial, duo editorial, menor editorial
del editorial » el editorial, de editorial, red editorial
los editores » los escritores, ril editores, los factores
dos editores » dos escritores, los auditores, ril editores
por medios » por medio, los medios, por dios

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: por medios, tu ((((dos editores) OR (los editores))) OR (((del editorial) OR (delos editorial)))).~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "por medios, tu ((((dos editores) or (los editores))) or (((del editorial) OR (delos editorial)))).~".
• Adding a wildcard symbol may retrieve word variants: por medios, tu ((((dos editores) or (los editores))) or (((del editorial) OR (delos editorial)))).*.
