Search tips to power your search.

To focus your search and quickly find the most relevant information you can give LOIS specific instructions:

 “Phrase search”                 To search for a phrase, add speech marks to narrow down your results. 

                                             Operators are connecting words which instruct LOIS to narrow or widen the search: 

AND operator                     Use either the word AND followed by a space or & symbol to narrow down a set of results.

For example, to find records containing all the words Sintering and Zirconia, enter either:

• Sintering AND Zirconia

• Sintering & Zirconia

• Sintering Zirconia (LOIS will use AND by default)

All the above will return the same number of results.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

OR operator                        Use the word OR between words to widen your search and increase the number of results.

For example, to find records containing either Ceramic Matrix Composite or CMC, enter:

• "Ceramic Matrix Composite" OR CMC

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

NOT operator                      Use the word NOT between words to narrow your search when you have identified a word you don’t want.

 For example, to find records containing the word Sintering but not the word Zirconia, enter:

•  Sintering NOT Zirconia

Be careful using this, as you may remove some useful results. For example, where both zirconia and another material are in the same record.
