Keyword search
You can enter keywords in 4 seperate ways and they all return different results.
- A single keyword
- Two or more keywords seperated by a space, this is like using the OR boolean
(eg neutron diffraction)
- Two or more keywords seperated by a +, this is like using the AND boolean
(eg neutron+diffraction)
- Placing double quotes around keywords will search for a phrase
(eg "neutron diffraction")
You cannot mix the various types of searches at this stage.
