Problem with QSortFilterProxyModel

I am trying to get a QSortFilterProxyModel to filter a table based on two inputs. The first input is a string that can have wildcards in it while the second one is a dropdown which shows the names of all the columns in the table.

When the user enters a string in the first input and selects a column I call the model and set the QSortFilterProxyModel in the way shown below.
Code:

// Find button pressed QString searchValue = ui->keywordLineEdit->text(); QString searchField = ui->fromComboBox->currentText(); QString searchFilter = searchField + "=" + searchValue; qDebug() << "Searching for " << searchValue << "from" << ui->fromComboBox->currentIndex() << "!!!"; if (!searchValue.isEmpty()) { model = new QSqlRelationalTableModel(this); model->setTable("Products"); model->select(); QSortFilterProxyModel *filterModel1 = new QSortFilterProxyModel(); filterModel1->setSourceModel(model); filterModel1->setFilterRegExp(searchValue); filterModel1->setFilterKeyColumn(ui->fromComboBox->currentIndex()); filterModel1->setFilterCaseSensitivity(Qt::CaseInsensitive); ui->tableView->setModel(filterModel1);
This does not seem to show anything in the tableview. Could anyone help me by identifying what I am missing?

Thanks,

It seems that every time I ask a question the solution comes to me immediately afterwards.

I am sorry for posting questions and answering them a few minutes later. It seems that I need to trust myself to find the answer a little longer.

I solved this by changing the
filterModel1->setFilterRegExp(searchValue);
to
filterModel1->setFilterRegExp(QRegExp(searchValue, Qt::CaseInsensitive, QRegExp::FixedString));

This seemed to do the trick even though I think I tried this before but something else must have been the problem.

Thanks and sorry for the redundant post.
