+## Search Queries and Precise Searching
+
+You can customize the queries to get better results.
+
+Given that, no colon ":" suffixes the term, then the default query is constructed for text searches. The default query is:
+
+```text
+(cm:name:"[term]*" OR cm:title:"[term]*" OR cm:description:"[term]*" OR TEXT:"[term]*" OR TAG:"[term]*")
+```
+
+Note that compared to Share the following defaults are removed from ACA:
+
+```text
+OR ia:whatEvent:"[term]*" OR ia:descriptionEvent:"[term]*" OR lnk:title:"[term]*" OR lnk:description:"[term]*"
+```
+
+### Key facts
+
+If you have entered more than one word into the search input box, then the search query is constructed automatically using an `AND` operation.
+
+I you have entered more than one word encapsulated in quotation marks, then the search query is constructed treated everything as a single string.
+
+If you have entered more than one word separated by `AND`, then the search query is constructed using an `AND` conjunction.
+
+If you have entered more than one word separated by `OR`, then the search query is constructed using an `OR` disjunction.
+
+If you have entered an `=` symbol before the search term, then the search query is constructed using exact term matching.
+
+### Examples
+
+| Search Type | Search input | Expected result |
+| --- | --- | --- |
+| Single Term | banana | Nodes that contain the term **banana** in any content | 
+| Conjunction | big yellow banana | Nodes that contain all of the terms **big**, **yellow**, and **banana** |
+| Phrase | "big yellow banana" | Nodes that contain all of the terms **big**, **yellow**, and **banana** |
+| Conjunction | big AND yellow AND banana | Nodes that contain all of the terms **big**, **yellow**, and **banana** |
+| Disjunction | orange OR banana OR apple | Nodes that contain at least one of the terms **orange**, **banana** or **apple** |
+| Exact term | =orange | Nodes that contain the exact term **orange** in any content |
