Perhaps you should try some spelling variations:
ionization segmentation » ionization fragmentation, localization segmentation, minimization segmentation
segmentation methods » segmentation method, documentation methods
methods function » methods functional, method functions, methods auction
basis linear » basics linear, bases linear, mass linear
based linear » based nonlinear, based library, based lead
basic linear » quasi linear, basic life

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

• Performing a fuzzy search may retrieve terms with similar spellings: ionization segmentation methods function ((((basis linear) or (based linear))) or (basic linear))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ionization segmentation methods function ((((basis linear) OR (based linear))) OR (basic linear)).
• Adding a wildcard symbol may retrieve word variants: ionization segmentation methods function ((((basis linear) or (based linear))) or (basic linear))*.
