# Description The syntax search allows for free logical combinations of all available search fields. While similar to the structured search, this endpoint offers much more flexibility at the cost of obscure search parameters. # Examples - **Geometry**: Search for the term <em>Geometry</em> in <strong>any</strong> field. Queries are <strong>case-independent</strong>. - **Funct***: <strong>Wildcard</strong> queries are specified by <u>*</u> (e .g. <em>functions</em>, <em>functorial</em>, etc.). Otherwise the search is <strong>exact</strong>.''Topological group'': <strong>Phrases</strong> (multi - words) should be set in <u>''</u>straight quotation marks<u>''</u>. - **au: Bourbaki & ti: Algebra**: Search for <strong><u>au</u>thor</strong> <em>Bourbaki</em> and <strong><u>ti</u>tle</strong> <em>Algebra</em>. The <strong>and-operator &</strong> is default and can be omitted. - **Chebyshev | Tschebyscheff**: The <strong>or</strong>-operator <strong>|</strong> allows to search for <em>Chebyshev</em> or <em>Tschebyscheff</em>. - **Quasi* map* py: 1989**: The resulting documents have <strong><u>p</u>ublication <u>y</u>ear</strong> <em>1989</em>. - **so:Eur* J* Mat* Soc* cc:14**: Search for publications in a particular <strong><u>so</u>urce</strong> with a <strong>Mathematics Subject <u>C</u>lassification <u>c</u>ode</strong> in <em>14</em>. - **cc:*35 ! any:elliptic**: Search for documents about PDEs (prefix with * to search only primary MSC); the not-operator ! eliminates all results containing the word <em>elliptic</em>. - **dt: b & au: Hilbert**: The <strong><u>d</u>ocument <u>t</u>ype</strong> is set to <u>b</u>ooks; alternatively: <u>j</u> for <strong><u>j</u>ournal articles</strong>, <u>a</u> for <strong>book <u>a</u>rticles</strong>. - **py: 2000 - 2015 cc:(94A | 11T)**: Number <strong>ranges</strong> when searching for <strong><u>p</u>ublication <u>y</u>ear</strong> are accepted .
