In OMIQ you will find yourself selecting single files or lists of files quite often. When searching for files not only can you search for the visible file names, but also for any metadata values you have within the Dataset.
OMIQ also includes a set of Boolean Operators to help make this process more efficient.
Metadata Search
Whenever you are offered the chance to type a filename in OMIQ for the purpose of filtering the available options, you can directly search for the available metadata.
For example, if within a Dataset you have Metadata set up with values of "healthy" and "diseased", we can type these metadata values directly into the "Choose File(s)" field and we will filter the availabe files.
In this example, we have searched "healthy" and even though the filenames do not include this information, we are given the two files which match this metadata.
Boolean Operators
To make this process more efficient, you can include operator search terms to combine and filter on different metadata options, as below:
:: will restrict the search to a specific metadata column rather than across all metadata columns
For example: Batch::12
Will find only the files with the value "12" under the column "Batch", and not reference any other values of 12 in either filename or metadata values.
! will provide a reverse search
For example Batch::!12
Will find all of the files without the value "12" under the column "Batch"
&& enables a compound search
For example Day::90&&Patient 3
Will provide the files which are both the value "90" under the "Day" Column and include the Metadata "Patient 3"
OMIQ Metadata search will also return partial matches when searching too.
For example D::90 will return the same options as Day::90
