Basic
searching
To enter a query, just type in a few descriptive words and hit the
'enter' key (or click on the Search button) for a list of relevant
articles. As only articles that contain all the words in
your query are returned, refining your search is as simple as
adding more words to the search terms you have already
entered.

Phrase
searching
Search for complete phrases by enclosing them in quotation marks.
Words enclosed in double quotes ("like this") will appear together
in all results exactly as you have entered them. For example, to
find articles containing the phrase thermal conductivity,
your search should be as follows:

Boolean
searching
Searching with the logical "AND", "OR" and "NOT" operators is
supported. In addition, search terms can be clustered using
brackets (). For example, to find articles about thermal
conductivity and metal that do not include the words
isotope or impurity, you could use the following query:

Word
variations (wild cards and stemming)
Searches using wild cards and stemming are supported:
- Wild cards. The wild card "*" may be added to search
terms. For example, searching for "crystal*" will return results
for articles on "crystallography", "crystallization", "crystals"
etc.
- Stemming. This option can be selected by checking the
"Use stemming" box. The stemming algorithm takes the search term
and removes common suffixes, such as plurals and "ing" endings, as
well as some other English language structures such as "tional" (as
in "rotational", where the root is "rotation").

Exclusion
of common words
Common words and characters such as "a" and "now", as well as some
single digits and single letters, are excluded from searches as
they tend to slow down searches without improving the
results.

Search by
volume
As a default, all searches are carried out against all volumes
available from International Tables Online. You may also select single volumes or
combinations of volumes for your search. If you are using a PC,
volumes can be selected by holding down the <Control> key;
on a MAC hold down the <Option> key. There is also an option to search on all volumes and Crystallography Journals Online.
