Main query form. Three types queries can be performed using this form. The appropriate query is performed based on which text boxes are filled upon submission of the form. The first is a simple query for retrieving sentences that contain either a certain interaction-indicating term or a biomolecule, depending on which text box is used. The second type of query is for sentences that contain two biomolecule name terms. There are two text input fields for the two biomolecule name terms of interest. The third type of query occurs when all text boxes are filled. This query takes two biomolecules and one interaction-indicating term, and returns sentences that contain the three terms. There is also an option to return a random set of N sentences.
