Perhaps you should try some spelling variations:
data documentation » apa documentation, fao documentation, a documentation
documentation 2 » documentation _, documentation a, documentation 1
quasar based » qsar based, sugar based, radar based
pulsar based » pulse based, nuclear based, sugar based
laser based » water based, cluster based
2 curtan » _ curtain, _ cartan, _ curtin

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: ((((quasar based) OR (laser based))) OR (pulsar based)) data documentation 2 curtan-metragem~.
• Adding a wildcard symbol may retrieve word variants: ((((quasar based) or (laser based))) or (pulsar based)) data documentation 2 curtan-metragem*.
