Perhaps you should try some spelling variations:
"sequential networks. historical studies" » "terrestrial networks. historical studies", "sequential networks. historical survey"
"sequence networks. historical studies" » "sequence networks. historical survey", "reference networks. historical studies", "service networks. historical studies"
"frequency networks. historical studies" » "frequency networks. historical survey"

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: (((((("sequence networks. historical studies") OR ("frequency networks. historical studies"))) OR ("influence networks. historical studies"))) OR ("sequential networks. historical studies")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"sequence networks. historical studies\") OR (\"frequency networks. historical studies\"))) or (\"influence networks. historical studies\"))) or (\"sequential networks. historical studies\"))".
• Removing quotes may allow a broader search: (((((( sequence networks. historical studies ) OR ( frequency networks. historical studies ))) or ( influence networks. historical studies ))) or ( sequential networks. historical studies )).
• Adding a wildcard symbol may retrieve word variants: (((((("sequence networks. historical studies") OR ("frequency networks. historical studies"))) or ("influence networks. historical studies"))) or ("sequential networks. historical studies"))*.
