How to



Searching

acsearch.info uses a so-called Boolean full-text search with the following operators:

Operator Description
* The * (Star) serves as a placeholder and can be used at the beginning or at the end of a word. It is automatically attached to words with three or more characters to generate as many search hits as possible.

Examples:
  • sest* finds all records starting with sest, f.e. both Sesterz and Sestertius.
  • *drachm finds all records ending on drachm, f.e. both Tetradrachm and Dekadrachm.
  • To expand the example given above, it is also possible to use *drachm* to also find all German forms like Tetradrachme.
"..." When searching with quotation marks, only exact matches will be delivered by the search engine.

Examples:
  • "T CAESAR VESPASIAN AVG" only finds records including T CAESAR VESPASIAN AVG in this specific form, thus ignoring a record such as T CAESAR VESPASIANVS AVG.
  • It is possible to use placeholders (*) within quotation mark searches, f.e. "T CAESAR VESPASIAN* AVG", thus finding both T CAESAR VESPASIAN AVG and T CAESAR VESPASIANVS AVG.
  • The placeholder may also replace full words, f.e. "T * VESPASIAN AVG". This query will find records such as T CAE VESPASIAN AVG, T CAES VESPASIAN AVG, T CAESAR VESPASIAN AVG, etc.
(...) Queries using brackets order words into subgroups.

Example:
  • A query for augustus (denar aureus) finds all records containing either the words augustus and denar, or augustus and aureus enthalten.
- A preposed – (minus sign) excludes a word from a query.

Example:
  • aureus -augustus finds all records containing aureus, but excludes the ones that also contain augustus.
The various operators may also be combined in queries.
